Hopefully the market will skyrocket again and make another ATH when this time comes, when the world will become cashless and cryptocurrencies will be use as a payment, the only thing that is alarming for me is when the time that bitcoin's price will hit zero.

Not only we just focus on Bitcoin to be accepted in all areas but also with altcoins. Having this lead in one of the popular food chains in the world, it soon to be happen that some food chains players will follow.
