"Nearly 2.7 trillion won ($2.3 billion) have been lost to crimes involving cryptocurrency in the last two years, according to South Korean government data."
where do you see the improvements being made against crypto criminal activity. this can really hurt the price for traders/investors if conditions don't improve.
If you look at the history, you can see that even because of the usual currency, huge financial crimes were committed. And cryptocurrency is currently little regulated and, accordingly, crime will exist.
