For a technical analysis blogger, I think luck is really important. Sometimes it's just a coincidence that you just go long and it just goes up, and you just close your position and it just plummets. So, technology is very important, but it also depends on the right time, place and people.

Nowadays, there are often some popular coins in the market, and the increase in their prices is very exaggerated, which makes them very suitable for rolling transactions.

If you have a certain level of analysis, in fact, 100 US dollars is enough. Start with 100 US dollars and 5-10 times leverage. If a popular coin rises by 30% on the same day, you use 100 US dollars with 10 times leverage and continue to roll over the position, you can roll out thousands of US dollars on the same day.

Over the years, I have started with $100 at 20x leverage many times. If the coin price rises by 30% on that day (with the coin price retracing less during the process), $100 can roll up to $5000-10000.

However, however, however, 20x leverage has a very low margin for error; this basically only works in a one-sided market. If there is a retracement during the process, it is also very easy to be sent back.

Therefore, if you don't have strong technical skills or risk control, you must lower this leverage. For example, starting with 3x leverage offers a very high margin for error.

With $100 and 3x leverage to go long, you need a 30% drop to be liquidated. Generally, without a black swan event, such market conditions have a very low probability of occurring intraday. Moreover, we usually choose popular coins for rolling warehouses, making it less likely to be suddenly crushed.

With $100 and 3x leverage to go long, as long as this coin continues to rise and you are making profits, you can roll into the warehouse. Of course, it is important to note that only the full position mode can roll into the warehouse; the partial position mode cannot be rolled and needs to be closed and reopened.

These are essentially foolproof rolling warehouses; you can pick from the recent leaderboard of popular coins, those with strong MACD momentum, and on the zero axis. Just pick one randomly to get in, and it's very easy to make money, although it depends on how high it ultimately goes, but that is not important.

Because during the rolling warehouse process, your holding cost will continuously increase. At this point, you need to set a limit stop loss, for example, if your liquidation price is $10, then your stop loss should be set at $10.1. This way, even if you encounter a huge drawdown, at least you still have some funds left, and it won't go completely to zero.

Rolling warehouse trading is essentially about risking a small amount for a large return, which is the charm of the cryptocurrency circle. Therefore, when doing rolling warehouses, do not be afraid; generally, with $50-100 and 3x leverage to go long, for it to liquidate you, it needs to drop 30%, which is not an easy task.

So, everyone should try this kind of play more often. Of course, I always suggest that when you don't have a good level, don't rush in with large amounts of money. Start with $100 or $200 for initial preparation and try rolling the warehouse. If the results are not good, continue to optimize instead of blindly rushing in with large funds.

When you have no skills and bad luck, no matter how much you invest, it will all go to zero.

Don't forget, in the cryptocurrency contract world, it's about risking a small amount for a large return, not the other way around.
