All altcoins that are in the top 10 coinmarketcap are good altcoins and have the potential to generate huge profits to buy at the moment, but it all depends on the capital you will enter into your chosen altcoin, because if you have a large capital investment you will quickly make a profit, because now the price fluctuates so quickly. but if your capital is small, you have to be patient waiting for the market to recover, and I think it takes a long time.
