25x leverage is to much.
Anyone that use that amount to opened long position at a price around $119000 or at a higher price for bitcoin would have been liquidated.
I prefer to just go for 5x maximum which is better.
What I am surprised with are people trading with millions of dollars and still using leverage. If I am such people, I will not use leverage at all.
It really depends on your risk tolerance, risk-reward ratio, or risk management. That's not how leverage works.
Some traders use different leverage amounts depending on their entry, target price, and stop loss.
Just think that this leverage control is risk tolerance for every trade you do, and it also depends on what you analyze in the market and the predictions.
