What is your point? We were talking about banks taking on bitcoin "exchanges" as customers. Several have been closed already. Fact.
How on earth do you know how many $10K deposits are made at BTC-E or MtGox? You can't possibly know that from watching "trading". The two are completely separate, you do realise that don't you?
I was talking about the average trade volume. To cross the 10K mark, one should trade ~11 BTCs. I was talking about normal people (not day-traders) who purchase all their BTCs in a single trade.
And there are only around 60,000 people who own more than 10 BTCs.
