indeed not all new coins are bad or scam, we must be able to open ourselves to accept new coins, if we are always looking for a safe point by just investing in old coins then new coins that have good potential will not develop, with the development of technology will makes there are many changes that are better in crypto
every new coin usually brings more sophisticated technology than the old coins but there have been many cases that occur that new coins that have better development potential but how they are still not guaranteed in the future, so that people prefer to look safe so that don't lose money on their coins, that doesn't mean we don't receive new coins but only to really look for the best from the good for every new coin.
