Bukinvest (bukinvest.com) is quite a young program (only 17 days online), yet becomes too risky to invest in. And it's not about the program itself, it's about the time we live and invest in. The less days before deposit term expires the better.
Though this HYIP has enough plans to choose from: four plans offering 135% after 1 day, 75% daily for 2 days, 175% after 2 days and the last plan 4 pays 400% after 7 days. Anyway the program has made a number of cycles on all 4 plans, so now any new deposit can become your last one. Yet you still have some time to take a risk if you want to. The program may well last a cycle or two.
