Aside from BTC and some high market cap leading projects, there are a few big ideas to choose from:
The market cap must be small, preferably under 100 million USD (even under 10 million USD is better, ideally without major institutional investment in the early stages). A small market cap has the great advantage that a positive development can lead to a tenfold increase more easily;
The official team must be continuously active, with state media providing ongoing updates, and code being continuously optimized (which provides the possibility of ecological explosion); it’s best to have a concept because you never know when the trend might come along; ideally, it should still be in the primary market and not yet listed on major exchanges;
Do not heavily invest, do not heavily invest, do not heavily invest;
It's no longer easy to get rich quickly in this industry, but opportunities still exist that are much larger than in other markets. For large funds, holding onto Bitcoin while other funds diversify to find opportunities is the way to go, and the rest is just waiting; learning to wait puts you ahead of over 95% of people.
