Ethereum left and right,presented as a great opportunity,future currency etc etc etc then
....
this is the biggest problem in this market.
people read something on the Internet written by some random person who they don't even know and/or trust and they believe it because it is said over and over again everywhere they look.
i wouldn't call ETH scam. it is just a pump and dump, or maybe it is just me and a pump and dump is pretty normal to me.
you should not get your hopes up in these cases, get in and then get out soon. nothing except bitcoin has a solid future. the rest are all doomed.
