Every investment scheme has risk, and so has bitcoin. But bitcoin tends to have an upward trend regarding its price basically so if your strategy is buy and hold, you can be somewhat assured it will generate profit. Although news of bans and other negativities towards bitcoin sprouts every now and then, bitcoin's value as the biggest cryptocurrency remains the same. Keep the faith!
Bitcoin are a rivals to government currency, so government may seek to regulate, restrict or ban the use of bitcoin, but I agree that bitcoin will always survive. There are also a security risk, if thief gains access to a bitcoin owner's computer hard drive and steals his private encryption key, he could transfer the stolen bitcoin to another account, but the users can prevent this only if bitcoin are stored on a computer which is not connected to the internet. So any risk can be minimized if we know how handle it.
