#BTC创历史新高
When trading, you must learn to assess the size of the opportunity; you cannot always go in lightly, nor can you always go in heavily. Normally, you should engage in small trades, and when a big opportunity arises, you should invest fully.
Rolling positions is a tactic that can only be used when a big opportunity arises. You need to have enough patience to wait for that high-certainty opportunity to appear. What is a high-certainty opportunity? It is when there is a sharp drop followed by sideways consolidation, and then a sudden breakout upwards; at this point, the probability of a trend reversal is very high. You need to pinpoint this moment and get in from the start.
Remember, rolling positions only involves going long, not short. Many people feel that rolling positions carry risks, but I can tell you that the risk is actually very low, much lower than the risk of opening a position in futures.
If you only have 50,000 on hand and want to start with this amount, assume you open a position in Bitcoin when it is at 10,000, set the leverage to 10 times, but don't use the full amount, only use 10% of the position, which is 5,000 as margin; this is actually equivalent to 1x leverage. If you hit a stop loss, you only lose 2%, which is 1,000; that’s not a lot.
