mexicantarget, exuse me, you are the admin and the owner and it's up to you to decide about rewards and the rest.
But the reduction of both exchange ratio and withdrawal limit is toooo big.
VirtualPub demands a lot of work and time from a user.
Hope you change your decision.
I agree, also, if you are going to use a live rate, you should post the live rate and source you are using (seeing as you obviously have that info in the browser already).
The rate was .365 when I first noticed the message like 6 hours ago and it's down to .35 yet bitcoin has barely changed in price over that span...?!?!
We need details to legitimize that .3xx number
So lets say the game has a base bitcoin value of $1950 (half way between the 1200 and 2700 you mentioned), and at that rate, 1 credit = .5 Satoshi
If say
https://poloniex.com/exchange#usdt_btc has it listed at $2370 (current as I write this)
1 credits would be worth 1950/2370 (0.82278) * .5 = .411 Satoshi
This is the way I imagine you are doing it, just with a lower base to get a number at .35
So we only need TWO pieces of info which you are already using, you just need to show us.
Your base rate for 1 credit = .5 Satoshi (old site ratio)
Exchange you are using for current rate
I would be happy to consult with you on improving your site, just send me a message.
