The launch of EOS will change the playing field. I think it will make one of Bitshare's advantages go away, or at least neutralize it.
EOS will succeed, short of it being a scam (just joking). The only thing bitshares needs to fear is not doing the things it needs to do to retain its competitive advantage.
no it won't, i don't think the EOS dex will offer one cent trades, or zero interest loans. Trade on bitfinex and you will spend a fortune on fees. On the dex fees only cost one single penny.
