So you want to say that if you don't earn enough you will reset accounts?
This or I have to close the entire site.
Consider this like any other faucet. Once the wallet empties, it has to close. If this site never generates a profit, it doesn't make sense to keep it running at all - seeing as it is only emptying my wallets.
Its not any faucet since you don't buy upgrades on faucets with BTC, so all in all buying upgrades with BTC is not a good idea since they might be lost due to possible reset.
