To change the world using bitcoin I think it's pretty difficult, but I think it's nothing is impossible, I dare and try to change the world with bitcoin by accepting payments using bitcoin, although this is already done but I add to the extent of the range.
It is complicated to change the world with Bitcoin, as there is a lot of money being developed like Bitcoin like Ethereum or Neo, and if the world turns, it will get a lot of coins. Other and also Bitcoin is currently tending to increase in the coming months.
