Yes and yes .
Why is it a bad idea?
Instead of focusing on wagering 10btc just to increase your faucet amount, its better for you to focus on how you gamble your btc in order to get profit. Thats why it is a bad idea if you risking your btc just for faucet instead of profit.
Quite true ,
Its very hard to wager 1 BTC from faucet so you will have to deposit a big amount to wager 10 BTC and enable 2k+ Satoshi Faucet /
The reason why pd is earning big amount is because of the users who deposit btc to wager 10 BTC.
But mostly it fails and they end up loosing everything.
