I haven’t bought any crypto with fiat since 2015. My money goes one way from crypto to spending and my other small passive incomes mean I hardly have to touch it. Every now and then I cash a bit of BTC to fuel up my bank account, once it is in there I spend it, but I am always reticent to make those cash outs and I postpone them for as long as I can. Either way, I see and experience benefits to having access to both kinds of money personally. I am now free of the mainstream economy but I can make use of some of the qualities that I find useful. Any crypto that wants to be currency will need to be stable imo.
Yeah, as I said above, it would need to be millions per BTC to get close to being stable. If that happens then fine, perhaps it can be used for actual pricing and budgeting etc. We seem to be decades from that though, so there’s no way BTC could compete as currency in the short/medium term (whether it scales or not) - except where currencies are not stable or where censor resistance is essential for trade.
