I agree 100% with what you are saying, I do not think bitconnect will exist in 2-3 years.... Regarding the bot, to be honest, I think it can exist even without proof.

They do not always send return, and the system works quite simple to me.... when the market goes up you get returns, when the market goes down you normally get basically nothing (0.00%-0.05%).

Anyway my portfolio is currently divided in Buy-and-Hold for a solid 70% of my portfolio, Mining for a 20% and Bitconnect/trading for a 10%... As mining to be honest is giving so many troubles or missing opportunities I'm decreasing that part to increase the Bitconnect one. Maybe in 6 months from now I will just move to more buy-and-hold. As you know this market goes so fast that every month we are in a different scenario :)
