I might be missing something here but I think $150k will be the point that $0.002 gets rounded down to 1 sat. However what I was really trying to get at is over $200k is the point it negatively affects us by making the minimum payout more than the $0.002 it is costed for.
If I'm not mistaken, then Freebitco use 'round half up' and 'round half down' method for the faucet amount calculation. Therefore, we will receive 1 satoshi from the faucet if $0.002 becomes less than 1.5 satoshi for the price surge of Bitcoin. And the faucet will give 2 satoshi as long as $0.002 stays between 1.5 satoshi to 2.5 satoshi.
$0.002 will be less than 1.5 Satoshi when the price of Bitcoin reaches above $133.5k. And we will start getting 1 satoshi from that point for the 'round half down' rules. (1 ÷ 133,500) × 0.002 = 0.00000001498 BTC (1.498 Satoshi).
@hosseinimr93, Can you verify whether I'm right or wrong? You are good in this type of calculations.
I don't know how you made the calculations, but it is wrong.
