Everyone makes a mistake when trading or investing especially if you are just starting, which is bad but also a good thing to experience to learn from it and to avoid making mistakes like that again. I also made a lot of mistakes when I was just starting to trade/invest in cryptocurrency, wrong choice of coin, wrong timing, being too much greedy but I learned a lot from those so I don't regret that I made those mistakes. About Bitconnect, I never tried to invest on it even a lot of people are shilling it, saying that we can earn a lot of money from that cryptocurrency. But I just don't invest on something just because a lot of people saying that it is a good investment.
