Recently, I tried a small position and summarized my experience in playing contracts.
When the bitcoin price plummets, buy "low-market-cap hot projects, and the holding volume must be sufficient"
When the bitcoin price rebounds, sell it immediately
The winning rate will be very high
However, this method is not recommended for large positions. Try a small position first. Generally, if the timing is well chosen, the first wave of doubling the profit will be no problem.
