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
It may not mean a thing
Because it depends not just on the price increase alone but also on the trading volume that was involved in this price action, i.e. how much money got poured into the coin in question. Example, if a coin rose from 1 dollar all the way up to 10 dollars, that would be a tenfold increase (a rise of 900%), which may look an astonishing feat
But if this pump was on an extremely thin market like someone buying 100 dollar worth of coins, it won't bring in any real money as there is no liquidity that would make such a price meaningful let alone sustainable (read, it could plunge as fast and as much within as short amount of time)
