If Coinbase also wants to build a dispersed exchange, the 0x deal will be a huge help for the Coinbase exchange.
So I think this is a good time to invest in 0x.
I support your opinion. I think everybody understands that the future of decentralized exchange and 0x provides a ready-made Protocol. Of course coinbase may not implement it, but now is a great chance to invest in 0x. 2019 will be a breakthrough year for this project. If doubts remain, it is enough to look at the list of projects that have publicly announced the implementation of the Protocol on the official website.
