Theres a lot of these videos going around on youtube. You gotta think too that a lot of these people are making these videos to shill coins they are already heavily invested in. It's a red flag especially those people that were pushing bitconnect hard. I think the best strategy for now is the long term gain. Find coins right now that are significantly undervalued and that also have good technology and a plausible working product. There are still some good projects out there that can actually have everyday use as a currency.
