Last night I traded Bitcoin short-term options, starting at 9 PM with 50u, and continued until 5:30 AM. I slept until 12 PM, had lunch, and continued trading. Now my account has reached 1400u, and I will withdraw 500 to Binance to replenish the margin. I will continue to look for some shorts on dumb altcoins on Binance; as long as my position is small enough, these altcoins will have a day with 20 times profit and a 1000% gain. That will be the time for me to harvest.
