Since FPS (2009) in the UK Payments take seconds, not days. I'm not sure what you mean by virtual payments - all payments are entries in a ledger nowadays, they don't move physical money around. Re the Cyprus banking haircut I wouldn't be so sure you are protected from this kind of action - exchanges, developers and miners all have leverage and have already used it to fork entire currencies, and force changes on users, impose currency controls, impose local laws (KYC etc) if you want to spend and exchange the currency. I think on balance I prefer a slightly inflationary currency with low fees, few middlemen, and trusted counterparties and agencies to hold money (i.e. banks). Happy to ditch government control and our current system of money management though for deterministic inflation. I also prefer one which is not at the mercy of developers or miners, and does not attempt distributed anonymity, which places severe constraints on speed, energy usage and consistency, and did not have high fees. At present Bitcoin is completely unsuited to global trade and unlikely to improve soon. I think if you were a little more clear-eyed about the downsides of current cryptocurrencies, you'd make a would be more convincing case.
