well the new version will be more funny as i mentioned before ,since game is based on faucet system,the gold could stay,the diference should be the rate conversion....

if day 1 income of 0.25btc the rate could stant the way it is
if day 2 income 0.05btc the rate must go down for not take all pocket.
if day 22 income of 0.10 the rate can go high a bit soo users can convert it,

even if a user doesnt upgrade nothing and start just collect gold to convert it later well it will take a lot time since must upgrade to achieve a good ammount ,but well the new system may work or not we will see it as the new version goes live.
