how you can get return 5 bitcoin from investment 2 bitcoin
If you looked at the post, it's really obvious he referring to HYIP because he stated 48h investment while this kind of investment are really stupid and make you lose. Invest in 2 BTC is much better to put it to trading or business.
Investing in hyip not grow your bitcoin they have possible that your bitcoin loss because of them. All hyip are turn into scam the strategy of hyip they payout first the members so those members reffers more people and after that if they reach their target funds they will close their site and run all bitcoin that they have. Its better if you invest your bitcoin in trading for sure you can earn a lot of bitcoin but you cannot earn fastly in trading you need more patience if you do this.
