This is the way, even with 1-5% of what you have. Especially for the current state of the market. Be shrewd with your entry as the above posts suggests with its under $10 remark, and you’re almost assuredly gonna profit enormously in the medium-long term without ever losing a night of sleep from it.
I’ve been planning on doing exactly this with TQQQ and SOXL myself once they drop another ~40-50%. Though it should be noted I only have a small amount of capital to use compared to the OP (around 1% of the OP).
