No time is bad to trade your futures and margin markets, it all depends on you, especially on your preparedness in areas like speculation and management. Trading is always active whether we like it or not, but if it is a long-term buying and holding you are looking for, well, based on my experience, this is not the right time. The right time was the time the market was still very low. Those are the times the market was trying to change its trend, which was around late 2002 and early 2023.

If you had planned your trade well then and opened the trade, then it would have been good for you as you would have made money conveniently and might still be holding your buy position. What I do in such a situation is to look for the right support and resistance level to locate my stop loss while I buy the market. That stop loss will be very tight should in case my speculation is wrong. This is often done on either the 4H chart or on the 1D chart and it has been very productive.

Besides, you should use the risk-taking rather than the leverage, the leverage calculation often confuses as with 3x leverage, you can choose many risks unless you are referring to the maximum risk permissible by it, try to be specific next time. In all, if you use the leverage at the full stretch, then you might still get liquidated soon enough as €100 is little to plan such a trade with Bitcoin.
