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, if we invest in old coin, then of course we can find out which coin that have the potential for the price to increase and give us profit, because we can see the progress of the project and the volume or market cap of the coin, so it will be safer to invest in old coin instead of new coin, because new coin don't have much progress yet, so the possibility of the project can fail it will happen, therefore I agree with you to choose old coin rather than new coin.
