Bitcoin's utility these days is solely as a store of value or as a gateway crypto used for buying other alt coins.
It's strange to be saying this but the technology has moved on and as Satoshi Nakamoto has chosen to remain anonymous bitcoin has not moved with the times.
There are now a host of technologies which do everything bitcoin does, but faster and cheaper. Bitcoin Cash, Etherium, XRP and IOTA all bringing their own twist on blockchain or distributed ledger.
Bitcoins dominance of the crypto market cap is declining and it would be no surprise to see it knocked off its perch in 2018
I fully expect to see wide spread commercial adoption of these technologies in the coming months and years as they solve real world problems, the 'internet of value' is here to stay.
