Yeah you're right.
Planning buy some car right now, since already withdraw half just need to withdraw the half again. It's has been roller coster for me too, my waggering on Stake right now around 350,000$. I wondering how much for the monthly hahaha.
Since you have these kind of experience waggering.
Since you are deep in profit I would say something around 250$ monthly. I had 450k wager last month and got 330$, with a loss and platinum 6 account. You could get more for weekly actually if most of your wager came this week. If you have a host (guess you don't) you could also get the top VIP bonus. Could, not guaranteed.
Anyway, best way to finish this up is maybe set some hard wager/loss limits in their site and take a break, speaking from experience. You basically hit the jackpot so you should enjoy that. Don't fall into the trap in your mind that tells you "just ride it a little bit more". Of course you might win more but likely lose.
