Hmm, I think it is good for commercial purposes because it attracts or make people curious about it but I don't think many users will adopt it. The reason why is the high fees and rates. I would stick on the old way rather than using that.
I agree, people will still choose fiat over bitcoin because for sure they will be clouded minded what is bitcoin or maybe they are still being affected by FUDs.
Also if they adopt it, what will the government do? Taxed it? It will just increases the fee and on some way make the transactions watched or monitored.
They can't do it, that is the single thing that the Government cannot do to Cryptocurrency, it have a decentralized network called blockchain, but still peopel are afraid to use it for their own personal reason, maybe it is because they want to play everythin safe, maybe they are cowards, or maybe they just don't want because they thought it was something that is not like "fiat" at all. Also we don't want to work hard, we just want things that is easier to have like fiats.
