About the choice of a good token in my opinion is that you should see it on some of the major exchanges, like Binance, Kucoin or on some other exchanges. because if you buy on this exchange you can be sure you will be able to resell it without having to wait for the coin to be listing
binance listing give us guarantee for trading volume , majority coins or token have huge trading volume so we should not worry about its luquidity. mostly altcoin in binance have random pump from whales, it really excited if suddenly our assets pumped and we know it .
