Ask him about the new privacy feature that's coming to Bitcoin cash and how it'll stack up against coins with privacy built in. It seems the Bitcoin cash privacy will be off chain, mixing 2 blockchains. Kind of like what d.tube does with ipfs and steem. Some people think this mixing isn't ideal best to have the technology built into the chain. Also some people think privacy coins are going to take over. I think having a privacy option is good to have even on steemit would be nice to have some.
