Bitcoin has never been risky but seems risky to those who don't know about Bitcoin and have no knowledge of how to use Bitcoin.  People who are new to Bitcoin see Bitcoin as high risk, but experienced people disagree with the risk. Bitcoin is always safer than other altcoins.  In order to invest in bitcoins one must have knowledge about bitcoins, those who don't know about bitcoins I would say should not invest in bitcoins.  But I never recommend anyone to invest all their money in Bitcoin. You can invest 20% of all your money.
