Can you post here altcoin pumper groups and the links to them?
Poloniex is a biggest pump group, i think the link is poloniex.com
It`s true
But they only have about 30 altcoins on their platform. Yes they do and the reason is they are very strict on who get's in I read that you need at least 1 to 2 bitcoin to get in here I might say this is the official home of most whales so what ever they pump every body notice it.
