1. Coin Hoarding Method: Suitable for both bull and bear markets.
The coin hoarding method is the simplest yet the hardest strategy. It’s simple because it involves buying a certain coin or a few coins and holding them for more than six months or a year without acting. Generally, the minimum return is tenfold. However, beginners often see high returns or encounter situations where the coin price drops significantly, leading them to consider switching or selling. Many find it challenging to hold for a month, let alone a year. So this is also the hardest part.

2. Bull Market Dip-Chasing Method: Suitable only for bull markets.
Use a portion of spare money, preferably no more than one-fifth of your total funds. This strategy is suitable for coins with a market cap between 20 and 100, as they are unlikely to be trapped for too long. For example, if you buy the first altcoin and it rises by 50% or more, you can switch to the next coin that has dropped significantly, and continue this cycle. If your first altcoin gets trapped, just wait; a bull market will definitely release you. The premise is that the coin must not be too risky. This strategy is also hard to control, so beginners need to be cautious.
3. Hourglass Switching Method: Suitable for bull markets.
In a bull market, basically any coin you buy will rise. Capital acts like a giant hourglass, slowly seeping into each coin, starting with large coins. There is a clear pattern in coin price rises: leading coins rise first, such as BTC, ETH, DASH, ETC, followed by mainstream coins like LTC, XMR, BNB, NEO, DOGE, SHIB, etc. Then, coins that haven’t risen will experience widespread increases, like RDN, XRP, ZEC, etc., followed by various small coins taking turns to rise. However, if Bitcoin rises, look for the next tier of coins that haven’t increased yet, and start building your position.

4. Pyramid Bottom-fishing Method: Suitable for predicted large drops.
Bottom-fishing method: place an order to buy one-tenth of your position at 80% of the coin price, one-tenth at 70%, one-tenth at 60%, and one-tenth at 50%.
5. Moving Average Method: You need to understand some basics of candlestick charts.
Set indicator parameters to MA5, MA10, MA20, MA30, MA60, and select the daily line. If the current price is above MA5 and MA10, hold onto it. If MA5 falls below MA10, sell the coin; if MA5 rises above MA10, buy to build your position.
6. Aggressive Coin Hoarding Method: Focus on coins you are familiar with; this is suitable for long-term quality coins.
With a portion of liquid funds, if a coin's current price is 8 USD, place an order to buy at 7 USD. Once the purchase is successfully executed, place an order to sell at 8.8 USD. Use the profits to hoard coins. Take the liquid funds to wait for the next opportunity. Adjust dynamically based on the current price. If there are three such opportunities in a month, you can hoard quite a few coins. The formula is: purchase price equals current price times 90%, selling price equals current price times 110%!

7. Aiso Aggressive Compound Interest Method: Continue participating in small market events.
When a new coin's price increases by 3-5 times, take back your principal and invest in the next small coin, keeping the profits and continuously cycling.
8. Cyclical Wave Method: Look for coins similar to OP or APT that are 'black market' coins.
When the coin price keeps falling, add more to your position, and when it falls again, keep adding. Then wait for profits and continue to sell, repeating the cycle.
9. Aggressive Small Coin Strategy:
If you have 10,000 RMB, divide it into ten parts, buy ten different types of small coins, preferably priced under 3 RMB. After buying, don't worry about it. Don't sell until it triples to five times; if trapped, don't sell, just hold it for the long term. If a certain coin triples, take back your principal of 1,000 RMB and invest in the next small coin. This will yield impressive compound returns!
