This one looks interesting...based on Hedera Hashgraph: https://dropp.cc

uses both $USD and Crypto.

Only potentially bad? thing I see is the use of a proprietary wallet. It would be so much better from a consumer standpoint if they would all agree to a few standard wallets merely for ease of use and not having to having 20 or 30 different ones.

Thanks, as you say the issue with this is the need for a proprietary wallet to receive payments as this will add a fair amount of friction to the process.
