> And if you did need it, why wouldn't you just send it directly from your wallet, without the middleman? Isn't that the point of cryptocurrencies?

That's a good point but: Do you know the wallets of all your friends? The advantage of Signal is that it knows your social network.

I sign up for a mobilecoin exchange, do aml/ykc, buy cryptocurrency in some way, make a wallet in signal, have my friend make a wallet, then I send them mobilecoin, which is useless to them unless they also sign up for an exchange to turn it back into something something sensible. Yeah that's made so much easier by Signal being in the loop.
