Underlying infrastructure and all that yes, but the interface on top also needs to be very good. And the "fiat ramps" as they say.
Bitcoin is pretty easy to use. I mean at least as easy as it comes in the crypto world. The usage issue is being solved with the Lightning Network pretty well I'd say. There is almost >2k BTC on LN now. So, the usage is definitely growing and it is more a matter of regulatory convenience now rather than technical convenience.
Same for the Fiat ramps. It is mostly about what regulation will allow which will determine how "adoption" grows. There is another way of looking at it though. Even without much regulation, Bitcoin has done well. People who take the time and effort, eventually find ways. Maybe it is better than bitcoin is for self-starters, rather than for those who need to have their hands held all the time to decide whats good for them financially. Most of those people should probably then just stick to Mutual Funds and shit.
It really isn't. For me and for you, it's easy but you can't argue that it's easier than fiat and fintech apps.
And I do love Bitcoin so it's not like I'm attacking it but when I first came to use it 4/5 years ago, the apps weren't great if you want your own open source wallet which was non custodial. It's better today but it's still not as easy and friendly to use as other fintech apps but that's a problem we may not be able to solve if you still want people to set their own fees, have their own coin control, have multiple spend, etc.
It's also an attitude that we have to change a little. Instead of saying to people boy, go stick to mutual funds and shit, I think we can also look inward and make things for the mainstream.
We keep saying mainstream adoption right? So shouldn't we act it also?
Bitcoin operation is indeed not very easy for novices. They are fundamentally different from the original bank payment operation methods, especially the most basic security measures such as the preservation of private keys. Quite a lot of novices eventually lost their bitcoins due to improperly kept private keys. This is a huge lesson for each of us. Bitcointalk has done a great job in the basic popularization of Bitcoin.
