To me there is still not any opportunity legit enough that induce me to invest my Bitcoins. Bitcoins are very prone to scam, once you send Bitcoin to someone, you can't claim it back unless one personally know the receiver. So better stay away from Bitcoin investments, soemething relatively better is altcoin investment, trading,etc.
I definetly agree with you mate, since bitcoin is totally anonymous in terms of transactions done or made it is prone to scam just like what happened last year to me, I tried to invest just like 20% of my bitcoin before but it turns to a scam and there is nothing I can do at the moment, my money was sent out to my wallet already, there is no one to blame but me who invested and trust those ponzi and scam.sites.
We cannot blame anyone for making loss by investing in those ponzi sites as it was our greediness which led us to make that move thinking that we will be increasing our bitcoins in a quick time but unfortunately it never happened so now looking at my past experience I have decided that I will stay away from those gambling sites and instead will prefer to hold my bitcoins in my wallet for a long term.
