May I know why you are leaving of the major coins of crypto space ? If you are already holding a big stash of them then you may go for more diversification otherwise you are about to commit a big mistake and they remain a life time mistake too. So, think about that and act accordingly.

I will not follow this suggestion as it might need a very large capital and it lacks the actual part of investments; due diligence. Yes, you are sounding like going blindly. That may lead to very big disappoints later. For example, if 25 coins get you big profits and 30 coins get you losses mean then you will be into problems.

I started loving waves. They proved their potential in recent times. When bitcoin and ETH was not into rising side, waves showed big rally by gaining more than 2x. Some people are expecting waves to replace eth, that may not happen but waves will stay with us as an alternate for ethetheum.
