I continue my learning with Binance, progressing slowly with BNB Chain Developer. I am in the BNB Greenfield module, which as far as I understand is decentralized storage on steroids. If it is more than just that, please write your clarification in the comments.
I liked the previous modules because they had practical exercises, creating an ERC20 token and an ERC721 NFT and deploying them on the testnet. I enjoyed that experience. However, without practical use cases for Greenfield, I find it hard to understand its existence and even more its benefit to the ecosystem.
On the other hand, I started the Blockchain for Business Sustainability course. I find it very interesting, although I struggle to follow along since my strength is not in economics.

Hello everyone! Here I am again commenting on my journey in learning Software Developer in Blockchain. As a good beginner, I have already completed the CryptoZombies course. Since last year, I have been taking the Binance BNB Chain Developer course. I have enough confidence to develop something. But therein lies my problem, finding that something.
One idea that comes to my mind is to implement a voting system in my country, or at least achieve a proof of concept. The contract that handles the voting is relatively simple, the problem is access control (that only verified citizens can vote) and delivering a Soulbound NFT as evidence of participation.
For the voters, a basic CRUD comes to mind, with off-chain validation. But being able to implement a relatively efficient storage solution is the issue. Or at least it is for me. A mapping?
Then comes the second problem, interaction between contracts. There I don't know whether to inherit or provide an interface. Adding to that is where to store the data.
Frustration is my worst enemy and I don't want to leave this project abandoned.
Finally, the training of citizens. Perhaps starting as a sectional project. Maybe I am overthinking it and getting ahead of myself.
Let me know in the comments if you have any ideas.

The Dark Side of TON: How Telegram Bots and TON Apps Are Scamming Users
TON (The Open Network) blockchain, originally developed by Telegram and later taken over by the TON Foundation, has gained significant traction due to its integration with Telegram and various on-chain applications, including bots and mini-apps. However, despite its growth, there are several concerns regarding TON, particularly regarding security, decentralization, and the prevalence of scams. Here’s a detailed breakdown of why TON has major issues and how Telegram bots and other TON-based apps scam users.
---
Key Issues with TON Blockchain
1. Centralization Risks
Validator Control: While TON claims to be decentralized, a significant portion of its validation power is controlled by a small number of entities. This makes it susceptible to censorship, manipulation, and coordinated attacks.
Tightly Linked to Telegram: Although Telegram claims to have distanced itself from TON after regulatory scrutiny, it still plays a major role in its ecosystem. This creates a risk where Telegram can exert control over the network’s direction.
2. Lack of Transparency
Unlike Bitcoin or Ethereum, where development and governance are open and transparent, TON has a more opaque structure. The foundation controlling the network makes major decisions without clear community governance.
3. Poor Smart Contract Security
TON’s smart contract infrastructure is relatively new compared to Ethereum and lacks robust security measures.
Many TON-based contracts are poorly audited, leading to frequent exploits and hacks.
---
How Telegram Bots and TON Apps Are Scamming Users
1. Ponzi Schemes and High-Yield Investment Scams
Many TON-based bots promise high returns on deposits, similar to classic Ponzi schemes.
These projects often lure users with staking rewards, airdrops, or yield farming opportunities that are unsustainable.
Examples: Some TON-based investment bots claim daily returns of 5-10%, which is impossible to sustain in a real market.
2. Rug Pulls on TON-based Tokens
Developers create a new token on the TON blockchain, promote it aggressively, and encourage users to buy it.
Once a significant amount of liquidity is in, the developers dump their holdings (rug pull), crashing the price to zero.
Since TON lacks effective decentralized exchanges (DEXs) with proper anti-scam measures, it's easier to manipulate token prices.
3. Fake Wallets and Phishing Scams
Many TON wallet apps on Telegram or unofficial sources have been reported to steal private keys or inject malicious code.
Users unknowingly install these wallets and lose all their TON assets.
4. Fake Telegram Trading Bots
Some trading bots claim to help users trade tokens on TON with automated strategies.
In reality, these bots often require users to deposit funds into externally controlled wallets, leading to total loss of funds.
5. Hidden Fees and Forced Fees in Bots
Some TON-based apps and Telegram bots claim to be free or low-cost but then introduce unexpected withdrawal fees.
Some bots require users to invite others before withdrawing their funds, effectively making them a pyramid scheme.
6. Fraudulent NFT Projects
Fake NFT projects on TON promise exclusive access, rare items, or high resale value.
Once users invest in them, the project team vanishes, leaving worthless NFTs behind.
7. Lack of Regulation and Recovery Options
TON operates outside of traditional financial regulations, meaning once you lose money, it’s gone.
Unlike centralized exchanges, where chargebacks or dispute resolution exist, TON’s lack of regulation makes it a haven for scammers.
---
Case Study: Popular TON Scams
1. "Investment Bots" promising high yield – Users deposit funds and later find they can't withdraw.
2. "Play-to-Earn" TON games – Require an initial investment but never actually pay users back.
3. Fake TON staking services – Claim to offer high APR but steal user deposits.
4. NFT launches on TON with hype but no real backing – Creators abandon the project after making quick profits.
---
Conclusion
TON blockchain and its ecosystem, especially within Telegram bots and apps, have significant security risks, centralization issues, and a high rate of scams. While the network itself is technically capable, its lack of transparency and regulatory oversight make it a breeding ground for fraud.
If you're using TON-based applications, it's crucial to:
-Avoid too-good-to-be-true returns.
-Use official and well-audited wallets.
-Be cautious of Telegram bots handling your funds.
-Verify token legitimacy before investing.

What's happening with the market?!
That's the question everyone is asking. One person opens their mouth, signs a document promising an economic paradise, only for prices to plummet minutes later.
But those of us who live by trends and technical analysis know that this is the normal cycle of cryptocurrency prices. Sometimes it's subtle, sometimes it's more aggressive.
If you don't want to enter the cryptocurrency market and die trying, check out the tools that Binance provides: Market Overview is the most basic tool, you can get a broad view of what's happening in the financial market and make informed decisions. A social tool is reading the articles on Binance Square, as it provides real-time data from other users, some beginners and others more experienced. Binance offers more tools for more experienced users, but that's another article.

Analyzing how to start creating a smart contract, there is the easy way, the simple one, and the complex one.
The easy one is to use Remix IDE, but the problem is that it is an online environment. Not very friendly if the internet connection is unreliable. This leads me to analyze "offline" options.
The simple one, Hardhat. It is the framework backed by the Ethereum community and the most recommended right now. Personally, I like it because it doesn't require many things, it installs as a project dependency, initializes, and you have what you need available. But I feel that its parts are not completely connected.
This leads me to the complex one, using the Truffle suite, which consists of a framework that is installed on the system. Accompanying it is Ganache, a blockchain simulation that runs locally. Truffle was the first framework for the development of smart contracts.
What I like about Truffle is that it has commands to create the parts or everything necessary to start writing a smart contract, testing it, and/or deploying it. Perhaps my familiarity with tools like Artisan makes me see this tool as easier to use than Hardhat.

I will be honest with you: I am not a trader, not even close. I believe I have lost a total of about $500 in the last year trying to understand the indicators and making trades.
I am a developer who mainly works with Javascript and PHP, using the Angular and Laravel frameworks. That is what I do know how to do. And I am going to delve into the world of developing Smart Contracts with Solidity. Yes, I know, one more to the group.
What surprises me is that there hasn't been much information or tutorials in the last 2 to 3 years. The platforms that have something updated use their own platform to skip certain steps that, as an independent developer (and in bankruptcy), are very important!
So I am going to create a 30-day challenge to progressively understand the strange concepts of Solidity and in the end be able to carry out a project where the community can collaborate with me and I can give back to those who have lost with those "airdrops" that have only given out scraps.

A lot of cryptocurrency information is transmitted by communities on Telegram. Especially about airdrops.
One caught my attention, from the MINT network I think. But when I went step by step and read everything, I realized that one in particular is a wallet drainer, because when I signed up (a process that usually has no cost or is very low), it appeared to me that it was taking ALL the funds from my wallet.
Be careful! Check every step you take. This time of low prices is ideal for scammers to take advantage of people who want to enter the world of cryptocurrencies.

I said it in December and, although the price between January and early February was high, the price of $BTC , $ETH , $SOL and the other altcoins followed the annual trend, down in the month of March. Not as far as I expected, at 72000, but it was close, around 78000. In any case, the correction is taking place, so the price should recover and hold until the end of the year.
See you in the next "bull run".

Memecoins are a way to make some quick money... It all depends on the investment volume and the time you invest. Obviously, not all memecoins will be listed on CEXs, many barely get listed on several DEXs. This seemingly is a quality that contributes to their price and profit. We have several examples like $HMSTR , $CATI , among others...
The main delivery method for these coins has been airdrops via Telegram bots. The users' sentiment is: "we are already tired." They take a lot of time, change the delivery rules at the last moment, millions of users participating... they already understand the idea.
The time for Telegram bots has ended (no one stays for the second season). The time for testnets has returned.
Testnets are nothing new. The compatible wallet is registered, a certain amount of test tokens is taken from a faucet, and transactions are made with other users. When the testnet ends its trial period and becomes mainnet, users receive a certain amount of tokens that can later be converted to USDT/USDC (when the respective contract is integrated into the network).

I'm not a professional analyst. In fact, I've lost a lot of money due to different situations related to cryptocurrencies (following bad advice from pseudo-analysts, binary options, various scams), but I'm good at recognizing patterns...
So I hope $BTC has a fall (as is its normal cycle) and in March it reaches 72K and by October-November it reaches 122K (at least).
What do you think?

《After the Margin Call — HBAR Price Update》
Bitcoin performed a dramatic up-and-down spike yesterday, with an amplitude of nearly 5000 points, ruthlessly ravaging high leverage once again. Today's announcement to make Bitcoin a strategic reserve did not stir any waves.
When Bitcoin reached resistance around 104000, it chose to retreat instead of pushing forward. The trend seems to have support around 101000, with resistance still around 104000, and further resistance still exists around 107000.
The margin call position for HBAR is around 0.31. If the price corrects to this level, it will slow down, indicating that the support around 0.31 is still valid. If this support is broken, the next margin call position will be around 0.25.
The reduction position is first considered around 0.35, then around 0.37. If there are any changes later, updates will be posted accordingly.
