You can also split USDC and USDT, start with USDC with low leverage and if the trend is bad, you open the other with USDT, safer, with higher leverage.

You are absolutely right, I never close at a loss, I prefer to be liquidated than to close, I think I do it in the hope that the operation recovers and returns to the price at which I opened 😁. That's what happened with Solana.
