Answering the topic of the thread, it's the only reason why most people are on Darwinex. The dream of attracting investors is harder than originally expected without miracle trackrecords. So Darwinia is the hope. Like you've mentioned, I currently have 200k (not useful now due to low volatility but still). The last time I had 6 figures was in a short two weeks period or so in my first year with Darwinex. If they end it today, most people will have absolutely no reason to keep a Darwin listed.
So yes, if you're still looking to build trading capital, you should focus on it. Just don't allow it drive you nuts, which is easier said than done. It's easy to get sucked into trying to speed up EX, etc so you can start competing. If you just relax and manage to get D-score into the 60s after a year or so, you will almost certainly get allocated with a >1% return per month and decent activity thanks to the 120 positions allocated now.
Of course if you have a few rich friends or have a way to raise >$500k-2m for yourself, you can ignore it. In which case, you don't even need Darwinex.
