Contract trading still follows this routine: short positions enter at a cost that directly turns negative, then slowly deduct money from you. To be honest, this operational method has become a bit tiresome. But on the other hand, the recent short entry points are actually quite good. The technical analysis of these two coins, RIVER and XMR, shows potential. Although VVV is volatile, it is mainstream, and if a suitable entry point can be found, the risk-reward ratio is still acceptable. I just hope the relevant authorities can optimize this fee system a bit more; I always feel that trading costs are being eaten up more and more.
