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?
The definition of pump and dump had been answered above me, you must understand that investing on altcoins are like dashcoin, monero and ethereum is high risk losing money, if you want make investments into ethereum classic I agree with you because actually ethereum classic is original ethereum.
