That's really handsome amount of money considering the price of btc today. Most of my RPs, I usually redeem it for free btc bonus, so can't accumulate much. Maybe, he is regularly playing the reason why he can accumulate that much of RPs. But curious also for how long he acquired those amount? Because in my pace , I will be collecting that amount maybe for years.

I do believe that there is a good situation where we get to suddenly realize encashing the reward point could be something really good when we look at it. I had 100k once and now I am at around 50k once again, and that is a very good amount when you get it. However it takes a while to get that, you do not get 100k very quickly.
You would have to be gambling for a while and I have been gambling a lot for the past few years and that's how I have been getting in . I didn't gamble too much and then I didn't get anything and eventually I started to gamble a lot more and that is how I ended up getting something in return and that is how I reached 100k and now to 50k, so it is not really easy.
