I want to say that in some countries financial literacy is much higher than in others, and this combined with favorable regulation creates a positive environment in which people are not afraid to invest in Bitcoin as in some other countries in Europe where the central banks practically call it a fraud.
Yep it's correct, I forgot to think about the financial status.Some people who're in third world or don't have a lot money also buy cryptocurrency, but mostly it's not Bitcoin because their reason to buy it to make profit in short time.
The moment when you can target the original creator of the Crypto currency, you lost half of the battle.... and when that entity can be forced to manipulate the code... then you are fck'ed. 
The original creator must be a rich person, so he able to tighten his security by hiring few body guards to protect him.As for manipulate the code, if their source code is private, how we know the "manipulation"?
