let's assume this 10.000 wallet is really from Huobi
1.higher in this thread there were allegations that
all exchanges ale tightly connected2.huobi is most secretive of exchanges from China, no public shows, Huobi profile on Bitcointalk - last post Feb, 2014
3.as to huobi - only guesses as for instance:
Okcoin/ Huobi is owned by China Government
https://bitcointalk.org/index.php?topic=1311139.04.
where are best friends of BigVern? in China (it is where to he had escaped)
now we can safely assume that his best friends are at Huobi
5.with BV military intelligence background : he could be cautious and already parked 10.000 with his anonymous close friends at Huobi
but now with new heat - this type of security would be not enough
BV now wants 100% perfect wash not 99.9%
needs fresh mixing
best possible mixing available = with use of existing exchange which has thousands and thousands of legitimate wallets anywaysimilar perfect wash stories were in all altcoins exchange closings : starting from 2014 Cryptorush Mintpal and so on : nobody even bothered to trace stolen coins
similarly with MtGox Bitstamp Bter - nobody really tried to trace stolen huge packs of BTC
