i hope that in the future more and more companies will be accepting bitcoin in the future
You are not wrong, but if you notice you will find that the companies have already started to join bitcoin and are adopting it as the payment system for their users to purchase with it and are doing any transaction with bitcoin.
Some little companies that has younger owners and some huge corporations accept it BUT the best is yet to come, there will be a time where even that old shop in the corner will accept it . That is the next logical step, we all have smartphones and you can download wallets there and buy/sell stuff thanks to it. A LOT more shops than 2012 do it now, a lot more will do it in 2020 , its only higher from now on , with laws and taxes on bitcoin , its getting more and more legit and I don't see how it will go down.
Since more people will own bitcoin and more people will know about it, the price will go higher as well, just if this 'hacks' and scams of some companies wouldn't happen we could have seen bitcoin steady over 1000$ for the past year. With zen and bitfinex and cryptsy and many more the price went lower , thats not a bitcoin problem , that was a company problem, I am sure it will go higher and many corporations will adopt it.
