"I only know Steem, EOS and BTS so I'm focusing on that! :)" - those are also very solid cryptos that can make you very rich in 2018 - my friend.
I keep telling myself I need to buy EOS and Bitshares again, but right now my money is mostly in Steem and Bitconnect.
Yeah it's looking very promising indeed...I'm mostly into Steem for now as it has so much utility for me, really looking forward to EOS though! Gonna host some Steem/EOS/BTS meet-ups here going forward...
