I'am not sure how Faucets could give you 1 BTC to be honest but well .. I got them from signature compaigns and for selling few digital goods (Steam gifts or Origin accounts) 
Faucets gave 1 BTC or more few years ago.. they were giving the same amount compared to today's rate if you exchange it to BTC.. one faucet gave me 0.3 BTC for a single claim.
