There are always risks in business and if you want to make BIG gains then you'll have to take BIG risks too. In last few months, Bitcoin hasn't moved much up or down after the January's hype and dump. So I don't think engaging in Bitcoin puts us at any risk.
And the bigger your investments the bigger is your fear and the more risk you will take. Bitcoin has not yet recovered today but let us just wait.
Crypto currency always assumes a certain risk. Without risk, profit would be impossible. The risk, of course, directly depends on the amount of your investment in the crypto currency. However, it still depends on the price level of the crypto currency, in this case bitcoin. The higher the price of bitcoin, the greater the risk of investing in your funds.
