When you go invest on a bank or investment firm they won't show you their trade history either. It's very obvious why, because you could try to reproduce their strategy and compete with them.
Here since nobody is a firm, when you hide your history is scary because you might be doing martingale or have 0 risk management which is scary. But either way, for me the most important is monthly returns and drawdown.
For that reason, I think that Tuni you need to be more stable on your monthly returns you can't go for 10 months doing well and then lose to -8.48% grow.
