Shouldn't all crypto be backed by bitcoin ?
How could a "Bitcoin Standard" emerge? For example, if you could pay for food service etc everywhere with bitcoin, would that be enough to essentially drive bitcoin as a backing standard ?
Since all this "crypto" is based on various free software... there's no way of stopping anybody from creating a coin that's not backed by anything.
Do you think that the exchanges care if the thing they're selling is backed or not? Well, maybe 1-2 exchanges from 1-2 countries.
And even if all would ban the not backed coins because of laws... one can make a new exchange, hidden, P2P where people are allowed to exchange again not backed coins.
So no.. it's not possible. Also it's likely that you have misunderstood both bitcoin and the other cryptocurrencies (and the relationship between them).
