In the past month, two top-20 streak holders lost their streak. Who will be next to go?

If somebody misses a day and uses a "streak forgiveness" that doesn't count. Their streak has to completely reset.

In the unlikely event that somebody loses their streak due to a bug, and then gets it reinstated, that doesn't count either. (If I have already resolved and then somebody gets their streak reinstated, I'll ask mods if they can un-resolve for me.) 

I will bet in this market, including on myself. I don't promise not to manipulate the market by deliberately losing my streak...

Close date extends indefinitely until somebody loses their streak.

If I spelt somebody's name wrong, I apologise. Please check if you're not sure who somebody is, and if I'll make a mistake I'll edit. (I think I can do that...)
