Freebitcoin Marathon. Part 4. +0,00003155 BTC. And a little contest

Hey. This is my Freebitcoin marathon.

Week # 4: 0.00045171 BTC (+0,00003155)
Week # 3: 0.00042016 BTC (+0,00002594)
Week # 2: 0.00039422 BTC (+0,00003285)
Week # 1: 0.00036164 BTC (+0,00021328)
Week # 0: 0.00014836 BTC

Freebitco.in site is opened in one browser tab. From time to time I press the button to get bitcoin. Once a week I publish the result here.

Very small contest:

1. You must be registered on my link .
2. During the week, get at least once a reward on the site.
3. Post in the comments to this post a part (for example, the first 15 characters of the address) of the bitcoin address (which was registered by my referral link).
4. I will choose a winner by chance.
5. Prize - 1 Steem.

Important: Do not play multiply - mathematical expectation against you.

Good luck.
