To me, the fact that cryptocurrency has a dark side is what make the technology even worth more investing in. Although the investment has nothing to do with me patronizing the bad aspect like using cryptocurrency for drug/human trafficking or money laundering etc but because since there's a bad side to the technology there's also a good side and it's just a matter of time before the general public realized that to embrace the technology but by then it would be too late and I would love to be among the smart investor that saw that good side before others did like privacy, faster transactions, transparency etc to be among the benefiting cryptocurrency elite.
