people around the world are not adopting bitcoin because of those thing in general

1- security
2- regulation

those two thing must be addressed in order to rise the adoption of bitcoin

the secuirty can be done by the exchage(so it's not even a bitcoin fault)

the regulation is on the way on some countries, but need to be speeded up and should be easy for average people, not something like "i need to take note of every transactions" or other things too laborious
