The market has been relatively sluggish recently, but I think this time the rise should have a good increase, the washout has been done quite a bit, but I won't do contracts, I will buy some spot when I see a suitable opportunity. Right now, I just refresh my backpack every week, previously I had also written an automation program to refresh about 100,000 U every week, earning around 200 points per week, participating in the fourth season weekly is about enough, and there isn't much profit from alpha either, but the cost is quite low, with a daily cost of 1.6 U. I earn 4 times the points by refreshing coins every day and can save some costs through reverse limit orders. Occasionally, I help users write some customized scripts for the cryptocurrency circle, and then I just continue to learn and look for opportunities.
