Get out of Solana or continue to increase margin?

Hello everyone, I urgently need some advice. I'm in the red with Solana with a stake of €750 (no stop loss, very stupid). Should I gradually increase my margin in the current situation so that my Liq level continues to fall? My Liq level is currently at 104 USD or should I accept the loss and learn from it instead of potentially losing even more money now? Thanks you for advice.
