Bitcoins investing risks

[pereira4]

I think that's a good list OP. I might add a "black swan" sort of risk. That is to say that an unknown flaw or exploit in the protocol could emerge. Or some other, as yet unconsidered, event. Perhaps a dramatic change in the free and open use of the internet? It's not risk free. 

I don't worry about those things. The internet is going to be decentralized eventually, and we the people will run it instead of centralized servers. Will not even need a ISP. Look up on Maidsafe and meshnet.

I think the bitcoin exchanges are not official and certified , and this is a big danger waiting
bitcoin traders as you saw in the past years many exchanges claim hacked wallets ,,,
and the holders just loose simply their money , also the security of personel wallets
not low , I don't think that's easy to hack a wallet , and its also impossible to generate
or Brute Force a wallet private key and that a big deal  .

Official certification isn't a guarantee that an exchange is solvent. Coinbace for instance, is the biggest bitcoin exchange if you look at it from the perspective of investments. While it seems extremely unlikely to have your deposited coins there stolen they still have never disclose whether they practice fractional reserve with user deposited funds. The best proof about their solvency we have is Andreas Antonopoulos reviewing them on February 2014 and saying that they do indeed have all the coins they're supposed to. Actual proof of solvency a good way for exchanges to prove that they're responsible with user funds. Other than that, a good level of personal security and not keeping funds in a third party's wallet for too long can also be proven vital.
