I think people getting wise to Tether is just about to explode. Probably 50% reduction in all cryptos in the next two days. Mark my words.
My personal opinion is , whenever the bitcoin price dropped, it is very normal because that is an activity of trader for increasing the volume. If some people judge cryptocurrency and bitcoin will die because it, I think they must look back about bitcoin. But it very possible bitcoin will die in the future because technology continues to grow.
