Guys, consider getting rid of the +13% in the rankings for the next competitions. According to the table I am up 40+ mBTC, I wish I were, I have barely got 13 mBTC as profit (and part of it with bets over my 5%). What is the point on it?, encouraging quantity over "quality" in bets?
Question: When you bet using Directbet's playing wallet the minimum bet is 1 mBTC, if your current bankroll were lower than 20 mBTC and you wanted to place more bets, your only option would be to send from an external wallet setting your playing wallet's address as the payout addres? (or to calm down and stop betting

).
The above situation seems very unlikely, though, just wondering... as well wondering, what is the lower your bankroll can get in this competition? (I think the worst scenario would be placing 5% bets and losing them all). According to my calculations you could finish with 24 satoshis, but I probably miscalculated something (for example, how many decimals are used to update the bankroll?).
Hello, at the end of the competition we will as usual analyze what happened and make any necessary changes. So we will talk about any possible issues at that time.
As for the betting situation, yes you could do just that. Pay from another address. You only have to keep setting as the payout address, the one you used to register for the competition.
As for the minimum your bankroll can get, I have not made those calculations. Your approach was correct though, keep losing 5% bet stakes.
If it does not meet the requirements of 50 participants with 70 valid bets, What is a competition be extended?
Yes as 98789 said, the prizes will be cut in half, if the minimum 50 qualified participants with 70+ bets, is not met. That information is explicit in the prizes announcement:
Important Note: The prizes above require at least 50 qualified entrants that place 70+ bets (including multi entries, see "Multi Entry" rule on the post bellow). If there would be less entrants, the prizes will be cut in half.
