I don't really get his prediction about there being 10 cryptocurrencies that rule the world. They'd either have to fulfill very different functions or be tied to national currencies somehow to support so many.
There's only one internet. There's likely to be only one currency that lords over all others that it's used on.
I'm sure there'll be thousands and more by that point but they'll face the same challenges that alts have now. Why would I accept one of them when I could have the real deal? Exchanging crypto takes very little time. People would constantly be changing into the daddy.
You could offer me Rapecoin for photos of my arse. I'd tell you to go away and come back when you're packing BTC.
I thought about this as well.
Even I don't see the nessacitiy to have 2 cryptocoins, as I see no use for LTC tbh.
But what do you think about that market cap, realisitc ?
you need security of another blockchain as a backup
also think of forex like people when they discover the bitcoin ecosystem, the best speculation tool so far discovered by mankind
then you have anonymity coins, bitcoin will not be anonymous ever and black markets are quite big although tax avoidance and privacy is perhaps a bigger market
meta tokens like counterparty working on bitcoin blockchain or again for diversification and other reasons tokens like ether with their own chain handling transactions
decentralized internet like maid - that's another use
centralized approaches like ripple and stellar could have a merit
if you think cost, all these options could have a cheaper although less secure alternative
i am sure my list is not complete so when you think about it again - 10 altcoins and these meta tokens could amount to a sizable chunk of bitcoin or perhaps (and very possibly) altogether surpass the value of the bitcoin marketcap.
