hi im a newbie here and I've heard that big alt coins like ethereal dash are "pump and dump" what does this mean? are they gonna crash soon? should i invest into them? or is it too late? what do you guys think of other alts like monero or ether classic... should we invest into the cheap alt coins?
Pump = Increasing the price of coin
Dump = Decreasing the price of coin.
I like monero but not for the ether classic.
If you're complete newbie and just read more on the beginner section or trading section.
