How much is the waiting time?
Waiting time is 300 seconds, he already said this. But don't misunderstand this thing - it's a gambling faucet! You can claim only if your balance is 0, that's shitty :/
And due to recent "cases" of faucet farming it can be increased to 10, 15 or even 30, or in extreme cases a ban may be necessary(some guys had faucet farmed over 0.5 btc).
