Unified response to everyone, you can first invest 20% of the funds. It has been consolidating around 0.5 for 15 days, and it is unlikely to continue to drop to zero. First, invest a small amount while ensuring there is enough margin. Do not use high leverage; I suggest 10x or 20x. You must have sufficient margin to feel at ease. Do not try to eat it all at once. My rules are: first, sufficient margin; second, low leverage; third, hold on patiently for the long term.
