Rolling a position sounds scary. In fact, it is much better to put it another way: adding a position with floating profits. Adding a position with floating profits is just a common technique in futures trading.
You don’t need to maintain 5 to 10 times leverage, only two or three times. What you need is to add floating profits and maintain two or three times the total position. Bitcoin is relatively safe, right?
There are only three situations where rollover is suitable:
1. The direction to choose after the long-term sideways volatility reaches a new low:
2. Buying the bottom after a sharp rise in the bull market
3. Break through major resistance/support levels at the weekly level
Only in these three cases do you have a greater chance of winning, and all other opportunities should be given up.
