But new alt coins that lists on CMC. under 1.5 marketcap using the total supply.
after the circulating supply comes. You'd have bought in at the right time and make at least a 3x.
Sell at that pump. and repeat. Know where the whales are and what exchange is hot.
I have tried the same thing you told. It's profitable sometimes but at some, the price of the coin goes on decreasing after being listed on an exchange.
If you are to do it, try doing it from coins with lower total supply and with zero or less bounty distributions.
