in the middle of another localbitcoins.com transaction. this time, with an amount of MXN200, the seller's fee is only $11 and the Oxxo fee $7 (both in pesos), so much lower percentage. plus I'm getting over .01 BTC (0.0243) so there won't be a penalty transaction fee.

difficulty to target calculation:

>>> '%064x' % ((0xffff * (2 ** 208)) / (2 ** -8))
'000000ffff000000000000000000000000000000000000000000000000000000'
>>> 2 ** -8
0.00390625

my dedicated server generates about 243000 hashes every 20 seconds, and it got 28 .004-or-better-difficulty hashes in 11.53 run-hours, so around 12 clock hours. that's 1 hash in 18016714, which matches pretty well with what one would expect for 24 bits of zeros, 1 << 24 = 16777216, if I'm thinking about this correctly. so a difficulty-one hash would take 256 times longer, which means every 4 or 5 days I should score a block at difficulty one. when it's at 2, as Americancoin is right now, it should take 8 to 10 days on average.
