I have a crypto debit card I can fund as needed and spend anywhere. In fact for me it’s faster and easier than any bank. It can be sent to anyone in the world and with a stack of a few different crypto debit cards can be spent immediately in pretty much any country in the world with their local currency. Yes currently the exchange fees are not great on those cards for exchanging to fiat, but the trend is down and improving.

If you’re using a crypto debit card than you’re layering the cost of a standard bank transaction on top of the cost of crypto. That just sounds like extra steps to do what I just did with my debit card at the convenience store 5min ago - which took seconds as well and required no steps to convert currency or load up from a wallet/exchange. I’m just not entirely sure what using your crypto debit card accomplished beside spending a currency that takes more work to utilize.

I have no counterparty risk, no confiscation risk. There are no extra steps, I don’t understand what you mean, moving funds to a bank or debit card at a convenience store is massively more complicated.

I open a wallet app and the paypal app, copy the deposit address from paypal to the clipboard, paste into the wallet, type the amount, hit send. 5 seconds later paypal receives it. With one button I swap any portion of it to USD on the paypal app. I do this in large enough amounts so the crypto TX fees are insignificant to get into paypal, and the conversion fees are also small.

Any extra fees are more than covered by the long term appreciation of the Bitcoin, which will obviously continue as governments worldwide are drunk of their own power to print.

one thing that's important to understand is that your experience is very different from someone that already has crypto, and earns crypto. for you, you have to go buy crypto first, and you won't do that. for someone that already has an inventory of crypto, its just get cash as needed.

for them its just crypto -> USD which is very fast. for me, in the US as a US citizen, that is 2 minutes up to $25,000. from a personal crypto wallet, to the exchange, to my bank or brokerage account. beyond $25,000 it is 15 minutes to 2 hours via domestic wire transfer.

so one likely unreported aspect of crypto is that it likely has reduced international wire transfers, and cross border transfers that are prone to error and erroneous reviews and holdups

for about a decade now I have paid people in other countries in crypto. and been paid in crypto from some revenue sources. and we both liquidated as domestic transfers in our local countries. specifically because we didn't want to bother with international bank issues and time delays.

even hedge fund and private equity fund administrators that are more competitive allow in-kind investment of new limited partners in crypto, for many years now

the other thing thats important to understand is that there is a growing group that doesn't want "money they can spend" because they are liquid. they can buy goods, services, invest, day trade, passive income all in crypto within the crypto ecosystem. and for other things they can get the cash when they need it, or simply use a debit card that is custodying their crypto and representing it as the local fiat currency

but truthfully, going from USD -> crypto is fast too. if you're a US citizen you just need to use wire transfers to the exchange. SEPA region can also do same day settlement.

your user story and assumptions are really antiquated and don't represent what's been happening for at least 10 years now. if it doesn't apply to you then thats fine and move on
