Participation in ICOs has always been risky. And we should be more careful now because of the especially since the number of scam ICOs has increased a lot over as a last years. Before joining any ICO, we should read the whitepaper of the project and do a detailed study of the project's team members.
I believe that investors who hold their coins now will gain huge profits in the future. Because especially after 3-4 years, I think coin prices will be much higher than their current situation.
People's belief in crypto or not believe is their own preferences. I believe in crypto. I am almost certain that crypto will be in a much better position, especially after 5-6 years. And the current declines in the market do not harm my belief.
If you're going to invest short-term, then I think you should choose Ethereum and Bitcoin. But if you are planning to make long-term investments, then I think it would be more logical to choose some of the altcoins in Top20. Because in the long term, I believe that more profit can be made from the altcoins compared to Bitcoin.
I'm now generally prefer on top 20 altcoins. I buy new tokens with only a small part of my money. And I plan to keep all the coins which I bought until 2022. Of course, I'm also trying to expand my portfolio by doing daily trading.
