If we look some previous day we can see everyday must pump one or more than one coin. And if start to pump then It continuously cross 50%-100% even 200%.
I just looked at
https://coinmarketcap.com/gainers-losers/, and damn, Ormeus Coin
1351.05% in the last 7 days? Lol, that's serious pump-and-dump.
I didnt catch that, it would have been a best buy if I had studied that coin under several analysis before it became pump but now it is already too late, the coin has been pumped, though they might still pump it furthermore but its too risky to get in to such coin now, sometimes is good to actually monitor them and see the ones one can take advantage on even though I know that many of us are holder but these type of coins is what makes a day trader cool money if they are able to detect it on time prior to its pump.
Basically, I have all the time to sit and study them because this is what I do for a living for now, trading.
