You have to sell some coins for bitcoin right away and always because it can help you not to lose too much but even to make a high profit. ICOs cannot invest anymore.
Fewer and fewer ICOs are getting listed every month and the success rate shows no sign of improvement. There may be good projects out there, but searching for them is like looking for a needle in the haystack. I agree with you. Depending on the future prospects, we need to sell some of these coins and tokens for Bitcoin as soon as we get them in our wallet.
