In summary, I won 100 BTC (150+ Mh/J bet), then lost 40 BTC (350+ Mh/J bet). Total = won 60 BTC from Micon.
Thanks for betting, Micon.
code rec'd, codes combined with C's btc-address system (although I had to dig out an Alpha version - seems the newest "btc-address" doesn't have the "escrow tools" menu (or maybe it's an older version that doesn't have it)
but anyway 80 coins rec'd, thanks again to mrb and others for setting an example of how gentlemen wager & then settle bets with each other.
