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.
Yeah, but that is true for any site where you buy something with btc. Same goes for mining sites, other ptcs with advertising, casinos, games, shops etc. You never have the gurantee that you can get back what you deposited. And what admin meant was that the way the site works and earns is same as in faucets.
