If Bitcoin will also grow rapidly as it did in 2016, it is likely that in a few years it will be used everywhere.
I agree to that. More and more people are liking the advantages bitcoin has over traditional fiat currency and are accepting it on their business. Moreover many poor countries have been using it and less of fiat. However it does need more acceptance and spreading.
Once the acceptance grows the prices are bound to increase and then traders can happily trade of large volumes as well.
