Because the price of BTC went from $200 to $350
Can you explain the relevance ? Are you buying bitcoins to support your faucet ? If you are, then what are you expecting from this ? Do you have some plan to build other services based on the supposed trust you are expecting to gain from this ?
Atm, I am using ad revenue that is generated to buy bitcoins for the website. The ad revenue the site makes is in fiat so when the price of Bitcoins goes up, I can buy fewer of them.
