I've been investing in various internet business opportunities and I am yet to see an online business opportunity that didn't go south. Crappy ones in less than six months, better ones in a couple of years. But even with the investments that last less than a year, one can take out initial investment and make a profit. At the moment, the bitconnect is paying( I know this because I have invested some money in to them), but for how long - no one knows, except the owners of the company. But I am not the owner, I don't control anything that goes in the company, I don't have any vote in which direction the company will go, I can not make any decision related to the company. So I think of it like this: The company is NOT my business, my business is my own invested money in it and in every company that I invest in, I only invest the amount that I can afford to lose and my priority NO.1 is to get back my initial investment as soon as I can.
