the most important thing to look at is the danger of virtual money, both from its function as a means of payment and also as a commodity.
Bank Indonesia said that ownership of cryptocurrency is very risky and full of speculation because it is not issued by the monetary authority, does not fulfill the characteristics of money, and does not have a clear legal status. Then, having no underlying assets that underlie its value, the price volatility is very high, no administrator is responsible for its issuance, used as regulatory arbitrage.
With such a profile, cryptocurrency also has a high level of risk in terms of security because it is vulnerable to hacking. Cryptocurrency can also be a channel for money laundering and even financing terrorism. So this is very dangerous. Investment in virtual money has no upper and lower limits so that when prices plummet, cryptocurrency owners' wealth will be eroded.
