I need to follow up with these guys.
Yes to the first ?, follow on to that also makes sense that once the monetary incentives tip..... the easiest way to integrate with them is probably just getting a Zircon wallet for ecobank and accepting Solana - and talking about Hive with anyone who actually pays in crypto.
In these theories I think everyone gives too much credit to everybody because even with HIVE accounts, further onboarding seems to require time and effort and continuous human contact. I don't know how much money it will take for merchants to jump that gap, but in my experience everyone is focused on their own thing.
I did make a lot of good contacts, some of which I'll follow up with one day. But there simply is not an incentive system I can imagine that can make it worth my while to handhold individuals or small and medium sized crypto projects instead of just focusing on building my own better.
