I think you're too humble. It's very easy to blow up a 300K account trading with leverage. I saw at least one guy on this board almost do it. He went silent, so maybe he actually did blow up. Another guy took 10K to 100K rather quickly and then lost it all again...
Consistency and managing drawdowns/risk is the hard part in this game, IMO.
There is never any excuse to blowup an account. Or exceed predefined drawdown limits.
If you never want to lose more than 25% of your account, that is almost completely in your control. You cant bet 2.5% on a trade or you can bet 0.25% or even 0.1%. So you can control your downside.
But drawdown duration is not under you control. You cant control how long a drawdown will last. And if you attempt to do so, you could just as easily make it last longer.
