https://freebitco.in/ are supplying us smaller and smaller each time. Is bitcoin slowly becoming rarer and rarer? I just started mining. So I hope that can help me. Please can someone answer this?
Popular faucet supplies it's users with a low amount of btc and is getting lower each day because of the rising price of btc and of course they adjust it so that they will still have some profit for themselves to sustain the site's hosting. If they would not do that, they would easily ran out of funds so they have to adjust each time btc price go up.
