Some are good and worth it to buy but so many are worthless and not recommended to invest in because there is no potential and project is not good,but there is sti altcoins that is worth it and profitable,dont quit investing but be careful on what you investing.
What you are saying is very unclear, I think everyone already knows where to invest and what coins to choose, because now there are so many places to check which coins and tokens are worth investing in, so don't float around saying something.
