until when we must trusted bitcoin become part our life?
What are you rambling on about? There is/should be no trust involved in Bitcoin.
I do not think that there is a timline until that bitcoin must have reached a certain level of peoples life.
There is no timeline and there can't be one. It comes down how involved the individual is with the ecosystem.
It's important to remind people that it's out there, and for those who use it, that they keep on using it.
It's rather more important to spread the idea and clear out the misconceptions caused by ignorant/uneducated people.
It's pretty much UP to you , If you want to trust , you trust otherwise just don't.
Bitcoin is not based on trust, it is based on math.
