why not try lakebtc.com??
you can control the market with 3000 btc volume!
In other words, his buy order will drive the price up significantly and cost him a lot more lol.
http://bitcoincharts.com/markets/ shows:
the 24h trading average volume of LakeBTC is only 2,000. BTC-e is also only about 2,000
and a little better, Bitfinex's is 4,000 Bitstamp's is 3,000
if you want to buy 3,000 btc, no matter where you can control the market, but you choose okcoin or others in china.
If I were you, I would choose the
LakeBTC or
BTC-e.
I can not enjoy the feeling of control over the market, but also because their smple and convenient transactions and lower fees.
