Aaaand here is my bet for the raffle:


It seems that what Loyce saw on the difficulty estimator website has changed since then. Right now, it shows that "Next Difficulty Change: between +2.7816% and +15.3994%". I will take a wild guess for a +3% difficulty, which would mean to have a block at each 10.3 minutes (10 minutes and 20 seconds).

Right now, lattest block is 770328, so, based on my calculation, there is space for 3840 more blocks. Therefore, my prediction is 774168!
