It's clear to me also crypto currency applications lacks lot of transparency, clarity, and lot of scam & malware around lol

But i guess it's also because it's early in the big bang, so lot of people want to take advantage of the hype by release not so finished applications, or use lot of phishing and copy paste like technics to grab some reputation easily by running their own crypto, while not having really the dedication other than to grab some money quickly.

For the terrorist funding, i guess it's unavoidable, and they don't need crypto for this, they already have their own circuit, and are very smart to hide their transaction even with the regular banking system.
