I have been really impressed with what I've heard from Hashgraph. The fact they're able to do transactions so quickly is crazy as compared to Bitcoin. While Bitcoin purposely slows down transactions to make sure they are legitimate, Hashgraph passes them at lightspeed. From what I understand there are already a number of banking institutions that are using Hashgraph. I think at this point, that's probably one of our frontrunners in terms of what will actually be used in checkout lines.

Hashgraph is my #1 crypto project. But thanks to US Regulation only accredited investors could get in. The project is valued at $6 Billion USD and there are many projects that are built on Hashraph and it's awesome to just read the news or the Medium blog.

Even Dash/PIVX are good for checkout lines. Hashgraph can be used to build the exchanges of the future.
