I see more and more acrticles of bitcoin being used for illegal activities
will this hurt bitcoin in the long run , will governments ban this just like they started to do wih paying in cash for some services
to harden the use of illegal , and money laundering
This is normal. And it will not hurt it. Actually I believe it helps Bitcoin on the long run.
If this surprises you, all (or most) currencies are used also for criminal activities.
The fact you hear about this in news, this helps. Because it's advertising. Because more people will hear about Bitcoin and more people will think it may help them in legal or illegal activities, more people will "give it a shot".
The aim of Bitcoin is to become a coin, i.e. be used by as many people as possible. (And secondarily, this will boost Bitcoin price too.)
