I think we'll see bitcoin more used for large transactions, some other coins such as ripple, litecoin and etherium are better suited to smaller, faster, cheaper transactions. Bitcoin is becoming like the gold that used to back fiat currency. We don't buy our groceries with gold, but it still has a value as a store of wealth.
Bitcoin isn't all bad either, I just got a bunch more ripple using bitcoin (using
changelly.com) and the transfer time from beginning to end was less than 15 minutes.
Ripple for example has very low fees, and transactions can be done in 4 seconds (or about the same as a credit card) and it's now being used by many banks as a transfer method.
