Did you look at the date of the message? At that time the course was mediocre. The coin showed excellent results!
Let's hope that someone took advantage of the OP recommendation and bought some Alephium, which really showed good price growth and is listed on exchanges such as MEXC and Gate. But now it is very risky to buy this coin, since the price is at its maximum values.
Good growth of about x20 since the OP suggested, I completely agree with you on the point that it has reached its peak state, and joining now is really a risk. There are not too many special things to analyze about its potential. I think that if you buy in a good position, you can absolutely expect to receive some more announcements about CEX in the future to be able to Increase the price more, but also be honest about the risks and profits, which should also be carefully calculated for those who intend to approach the project at the present time.
