I have started a poll just a couple of days ago about this exact topic:
Anybody here trying to live bankless (using Bitcoin / cryptocurrencies)?Response has bit a bit underwhelming, but there were at least three or four participants who lived "bankless" at least for some time, some of them (I think) from lesser developed countries. Tax payments and general service payments have been mentioned as obstacles, to a lesser extent also volatility.
In my country, I can pay some of my taxes in cash or with a digital wallet managed by a financial company which is not a bank (something like a "local PayPal"), but e.g. for the tax for small businesses a payment via bank transfer or debit card is mandatory, because the government wants to discourage payments in cash (although no "cash abolition" is planned).
Otherwise how do you plan to receive your monthly cheque or how do you plan to pay the recurring payments to pay the bills (water, electricity, ISP, phone, insurances, taxes, landlord...)? If you can not pay the groceries how will you pay the cashiers?
This depends heavily on the country you live. In my country I can pay almost all services with cryptocurrencies, but only via a third party payment processor company (which again, are not banks but also regulated and mostly have KYC/AML procedures).
How businesses could be created if they can't borrow money from the banks? It's what makes an economy growing, create jobs, etc
In theory this can be covered by Bitcoin P2P lending, or even by "Bitcoin banks". The main problem here is, however, volatility. If you borrow 1 BTC and just there is a Bitcoin rally, you'll have problems to pay it back. Thus, at this moment, the P2P lending market is not very developed (it exists mostly to provide capital to short sellers) and is not adequate for the "average Joe".
Volatility is also a problem if you got your salary in BTC and don't want it to lose value if there is a crash. (For the volatility problem I'm reseaching for a solution "without" centralized providers, see
here).
What about the average Joe using his interest account to earn a small profit annually?
Also here ... Joe would have to lend Bitcoins to someone and he would get paid interest for that. But the volatility-related risks are still to high for "average Joes".
Bitcoin isn't looking to replace the banks but rather to be an alternative, as a second layer (or as the first, as you wish)
I agree partially - banks will continue to exist even if Bitcoin was perfectly stable and had replaced fiat totally. They'll still have advantages managing risks, as they have the best algorithms for risk management (BlackRock's
Aladdin, for example) and lots of connections to the local economy (or to the "blue chip companies" in the case of bigger banks). But it's possible that some typical banking services, like a savings account, could be "taken over" by cryptocurrencies.
