No doubt they do.
A easy way to hide where the funds come from and anyone can access the funds.
Other than using a bank account and being traced.
What do you think?
I think so.
After all, we already know that criminals and drug dealers using bitcoin very long time.
ISIS proved already many times that Internet and social medias is their main promotion tool and weapon.
So, no doubt that they know about bitcoin and already using it.
Bitcoin is anonymous and decentralized, no government control.
So, it's perfect tool for them.
Using social media outlets, like Twitter, Facebook, Instagram, and so on is going to be something that is insanely different for a terror organization. I personally hold the view that their usage of Social Media is being used a scare tactic to hit the people that the West cares most about-- their children and the younger generation.
Plus, if these people are going to attempt to use BTC they're going to need to use BTC in combination with banks to be able to sell this off and get to normal currency. It seems like too much of a hassle for them to go through when they could be using cash which is MUCH BETTER at hiding as their is no paper trail when it comes to money.
So, no, not a perfect tool in the least.
