I believe the future of BTC is not being used as a everyday payment system, but it going going to become a big reserve of value.
Similar to what gold is today.
I too expect the same. Now itself bitcoin has evolved as a reserve equal to the gold. In future bitcoin technology will be used by banking sector for transactions and bitcoin will be used as a reserve.
Well I would certainly hope you're right but currently bitcoin seems to volatile and therefore very risky. With gold at least it is relatively stable in price and always has the intrinsic value of being a usable precious metal whereas bitcoin doesn't and therefor relies solely on what people are willing to pay for it.
gold is something different but in some was the same less risk someone will say on the other hand with btc you have tons on possibilities like investing in some other coin maybe or saving it for big jump
