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.
Well I don't agree with you because monero is the real heart of crypto currencies and I don't see a reason why they are high risk investments, yeah ethereum classic is good too but I would everytime prefer monero over it.
One thing we all have seen is that Monero has had never had a complete dump in price, since it is starting it has been going good.
