Transaction competition information update + today's review
I didn't expect the black swan to come again, all major coins have had a big pullback, causing my balance to be insufficient to earn 3 points, I'll wait until things stabilize a bit before adding more.
Don't touch the contract, I couldn't resist trying to short one hand a few days ago, didn't make any money, and lost 30 dollars in fees, what a mess, I'm still at a loss
