Bitcoin is already pretty widely accepted as a form of payment and a store of value. You can even purchase precious metals and pay with bitcoin. Soon you will be able to sell precious metals and get paid in bitcoin.
I think cryptocurrency is just getting started, will Bitcoin win out in the end, maybe not, but it has certainly paved the way and jumped a lot of hurdles, making it easier for other cryptocurrencies to be accepted as a form of payment and a trusted store of value.
