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?
They are giving us smaller amount each time because they depend on the price of the bitcoin,
As the price increase they would adjust the bitcoin that they could give so they are only depending the amount of the btc that they would give on the current price.
After all if they wouldn't do it they would be giving us a huge amount of btc right now I started claiming in that site when they would give about 25-20k sats per hour that's their lowest prize back then.
