look at the coins with a very large total supply, pay attention to the volume and money of these coins and buy them when they are cheap, then you bet someone will promote these coins in the future.
Or atleast your coin must survive in longterm.
Bet a lot on the next doge, today everyone got a suitable result, one that will probably end the trend of choosing altcoins that have a large supply and like to be pumped, pretty much liquidated today and I believe the bet was wrong, our lottery ticket has failed. Searching for such projects will give us two very opposite results but most of us are relying on pure luck, I do not recommend, our choices need more assurance, instead of looking for special opportunities
