In my opinion, As of now it is not advisable to invest your or our bitcoins because IMO it is better if we just keep it safe in our bitcoin wallets rather than taking risk on investments that may turn to scam or get negative profit.
It depends on the situation, someone may get a positive chance of investing his bitcoins where he would be sure that he is going to generate some profits for himself, but if someone thinks investing somewhere involves more than 50% risk then investing is probably not recommended.
