$ETH Brothers all say why every time I see the profits retreat, every time I have floating profits I don't close the position, because closing a position also requires opening one, it's meaningless to close it, take some profits, leave some positions to hold on, when profits retreat, I add to my position, this way I won't miss out, of course, this is under the premise of having logical support to judge the trend. Last week I also made a profit of nearly 30,000, although I earned a few tens of thousands less, but I have been in the market all along, the operator didn't wash me out.
