I am wondering how their trading system works. If I check the Bitcoin chart, I see that Bitcoin has not touched 87K in the last seven days. If their chart is different and the price fluctuates based on their on-site trading only, I am curious how it fluctuated when their website was offline. I am puzzled and wondering what the possible answer is. I am sorry, I am not a regular at Rollbit and have never used their trading system.
I also wonder if they offer something special based on your trading volume. Considering you are a trader who opens positions with thousands of dollars, why don't you use trading platforms or exchanges instead of a casino? The possible reason is they may give you some bonuses or what?
