what amount of risk is there in investing in bitcoins?

[Aya]

It's already a given that all kinds of investment include risk but we cannot pinpoint the amount of risk that Bitcoin poses. But one of the risks to watch out for is that since there is no central authority involved in this, if a hacker gets in and takes our money, there is really no one to whom we can complain.

Also, we should always remember that Bitcoin is highly volatile. Risks are inevitable so we should just be wise on our investment decisions.
