Re: VirtualPub.io - Run your own pub/bar, serve drinks, earn bitcoin!
if the bitcoin drops to $2500 i'm curious to see if this halving and ref comision percent will be reverted 
It will, but not to the same numbers.
Edit :
Regarding referral commission, which will be 2.5% from 10%, because previous owner charged lifetime buying of referrals 10k credits, which is 2k sat on current price while you get 2k sats per 1 withdraw of your referral.
Not fair to judge by this, 99% of the direct refs purchased are inactive (from people's reviews), this feature is a trap to be honest. I know the website since it was launched . I didn't exploited (used) deposit (by paypal) feature and i've warned tomos to not add paypal because it won't end up very well .And i didnt purchased refs, maybe only one at the 2016 Christmas, i don't remember, but i earned my 99% of the refs from advertising , by spending time and money.
