@root @katka @ocean Actually, Taler seems like the most stupid idea I have ever seen.
Where is the cash stored? Well, on your device.
What if you loose your device? Well, you lost your cash.
What if you want to refund a payment? Well, you cannot.
That could be alright and fair as crypto has the exact same downsides. However:
How do I make sure my bank will accept my Taler coins? Well, you hope they will?
They cannot just refuse, right? Well, you could complain to auditors and regulators if they don't.
Well, if they refuse to accept it, can I just keep holding that cash? No, since your cash EXPIRES.
How do I keep my cash then? You need to keep your wallet open, for it to exchange the old cash for the new.
Wait, but what if my bank doesn't accept my cash? You loose it.
What if I don't open the wallet? You loose it.
Is it at least free? Nope. Fees all around. Even if you fail a transfer.
How could you fail a transfer? Well, you need to make sure the receiver wallet is active.
