Always keep your bitcoin in a safe offline wallet people.
well you're lucky dude, you must be really grateful that you have never been scammed by some fake investments. for some people including me, we have been scammed by few fake investments and we have been very disappointed and frustrated by the outcome but still these experience made us better and wiser when it comes to that case.
I guess that you are young and never tried anything else in online world, only bitcoin.
If you tried different Revshare buss. opportunities, HYIP, trading, casinos etc. I'm sure you will have different experience.
You are right, Bitcoin is the best so you don't need anything else, really.
