Worse than that. The brain teaser becames nightmarish when you realize the alternative neo bank-like and electronic money institutions are no workaround to work with trading brokers. Because you won’t be provided a proper dedicated IBAN at your own name, which these services don’t offer (sub-account for you but the account really belongs to the company). Some have the appropriate IBAN but decide to ban some activities (this time cryptos, not forex)
Even PayPal / Neteller-Skrill can review how you use your funds and decide that your habits are not compliant at their will, then set limits, even block you. Other times, your account will be limited by design. Where I live, I can receive money on PayPal but cannot withdraw it to a local account, so I’m forced to spend all money through PayPal again at buying products / services.
Not even talking about the services that could fit but for some reasons have not spread outside of a restricted list of supported countries / zones, where you cannot open an account.
In the end, I only see crypto which was built in mind to prevent any abusive “last look” on money transfers : free money that cannot be locked or overlooked by stupid misaligned rules, no limits on amounts. To that extent, which is not the least, crypto is the LMAX of banking.
