Why does amount of payout at freebitco.in halves?

Freebitco.in (and its sister site freedoge.co.in) are the most reliable and trustworthy bitcoin faucets. But some users could eventually see the significant drop in payout for 0 - 9885 numbers. Amount of payout for these numbers halves, while other payouts for larger lucky numbers are seems to be OK.

I suppose that there is a problem with Multiply section of this site. When the amount wagered in this section drops below some level, site halving you payout. The solution is to try to multiply (or, at least, not lose) your satoshis or doges.

I use classic Martingale settings for that:

But you could try with lower odds and lower lottery payouts - you will lose less more than it is possible on above mentioned settings (same as described here). And, after some amount wagered, you free btc/doge payout will increase to normal level. Also, you will get some reward points at Freebitco.in

Have a nice play! What freebitco.in strategy multiply game do you prefer?
