Place Bitcoin according to its portion

Bank Indonesia gave a warning about the ownership and use of bitcoin. How do we see it?

"The Federal Reserve simply does not have authority to supervise or regulate bitcoin in any way"
- Janet Yellen, Chair of the US Federal Reserve, Feb 27, 2014

Everyone also knows that the currency that valid as legitimate payment in Indonesia is Rupiah, and for that there is a law, namely Act No. 7 of 2011 on Currency. Except on borders such as the border in North Kalimantan, the Ringgit or Dollar currency may not be used as a means of payment in Indonesia. There will be a sanction.

But if anyone can invest in stocks, gold, or hard currency such as Euro or Dollar, why when euphoria occurs in the field of cryptocurrency, then BI again reminded of the existence of the Law on Currency.

“Gold is a great way to preserve wealth, but it is hard to move around. You do need some kind of alternative and Bitcoin fits the bill. I’m not surprised to see that happening.”

- Jim Rickards, American Lawyer, Economist and Investment Banker

In fact, when viewed as an investment tool, cryptocurrency is similar to gold, and even more mobile, in the sense can be taken anywhere. When viewed as a medium of exchange (more to barter and not as a means of payment), then cryptocurrency can be equated with foreign currency that can be used as a barter based on the calculation of the respective exchange rate.

Even if it says that cryptocurrency is very risky because it is very volatile, all investors also know about it, so in general they make investments based on calculated risks. Then why do not we place it in its portion and see this problem in a digital perspective? Would'nt everyone bring their assets in mobile wallets in the future?
