People have wanted an online cash equivalent for decades. It's a privacy thing. "Illegal" means whatever authoritarian jerks want it to, so we can ignore that.

Ransomware obviously uses Bitcoin because it's reliable, and can be anonymized. And people use Tor for child porn and "illegal" drugs because it's secure and ~anonymous. They're popular because they work. And in a way, they're canaries for decent privacy lovers.
