the EASIEST way to get money into btc-e imo
bitinstant USD to mtgox

watch the mtgox and btc-e prices.  when the gap closes between the two (it got within like 4 dollars last nite, 138btc-e and 142mtgox):

1.buy btc from mtgx
2. withdraw and transfer to btc-e

generate profit from btc and ltc trading, but what i'd do is buy btc from btc-e, then transfer that to mtgox before converting to USD
