I prefer old coins with strong fundamentals to invest in when the market is down. new coins run the risk of being useless, unvaluable and difficult to recover. we see how many coins in the pancake lose their value even die.
I agree with you, old coins that already have products are safer to invest than new coins, because we can already see the progress of old coins that already have products and of course old coins will be more popular than new coins, so the price will definitely continue increase and give us profit.
