Either bitcoin will be worth a fortune in 10 years or it will be worth nothing. Either way, low risk/extremely high reward.
actually there are lots of other possibilities. two examples are:
- bitcoin price can stay the same.
- or my favorite favorite which i think will happen, is that price will rise slowly the same way it has been rising for the past 3 years and continue on rising this way, in that case it will be worth a lot but not a fortune.
Bitcoin ATM's are only increasing worldwide..... that might be the easiest method for attracting new "clients"
as my top comment said, ATM machines are not exactly the best way of buying/selling bitcoin and in my opinion it has no effect on bitcoin's adoption since people would have no need for an ATM machine if the shops accept bitcoin directly.
