Golem, antshares, Firstblood, SNGLS all got bought out in minutes by China whales or insiders raising 8+ Million dollars each. They got a lot of coins to sell you and a long time to manipulate the market.
I have no access to these information but ddid those Chinese whales ever dump their tokens?
If I have the 30% of the whole tokens I would be dumping them too and buy back after the rest have dumped their stashes. its what the usual traders do unless you just keep them and let it rot while the rest are in frenzy. it takes a year or two before one can see its development..
