Mario Draghi, president of the European Central Bank (ECB), has said that cryptocurrencies are not "mature" enough to be regulated.
Speaking at a press conference last week, CNBC reports, Draghi told reporters:
"With anything that's new, people have great expectations and also great uncertainty. Right now, we think that – especially as far as bitcoins and cryptocurrencies are concerned – we don't think the technology is mature for our consideration."
