Many coins are trash, but there are also good coins. The market gradually gets rid of bad coins, the main thing that you would not invest in them.
With current price developments, of course, the more poor quality coins will get very low prices and it really opens our eyes not to invest in these coins or indeed because the price of Bitcoin continues to fall so many altcoins follow the price. because in my opinion coin rubbish is a coin that doesn't have a high trading volume.
