Most of the crytocurrencies price are rising purely based on speculation and hype. But that doesn't last long when dust settles & hype vanish then only fundamentally strong crypto assets survive. Their are projects that have done nothing so far and are only papers and worth millions of dollars, they reached here just by manipulating the market and spreading false hype. But their are also legit project doing real ground work to make our life better, people follow their project on twitter/reddit or other platform and invest in them, they make partnerships with traditional organization, improve their network strength, solve real world problem and have use case.

When I invest in any crypto project I look at few points.

Read their whitepaper. Whats their project is all about, are they solving any real world problem or there any use case of this crypto asset.

Check their team. Who are their team members , whats their background or working experience.

Their project timeline/roadmap , how long do I have to wait for final product. are they delivering on time what they promised.

After I am convinced I invest a little and see follow their project development, if their project is legit their team is legit and working hard to deliver, then this cryptocurrency surely going to boom in near future.

Crypto world is full of scams and projects which can revolutionize the world, you have to choose the wisely.
