Person could also just not want the delta risk for the time it takes for the transfer.
Being fully invested in 1 security on 1 exchange is probably not a wise idea. You should have extra coin to send to BF and once your buy goes in, immediately sell on BTC-TC.
Also:
- you can get your bitcoin out easier, even it you do have to go through the awful weexchange.
WeExchange isn't so bad. Send your bitcoin to WeExchange and after 6 confs, you can instantly send it to your BF account.
WeExchange is actually there for a legal reason, not just to piss investors off.
Bitfunder have a more legally informed approach whilst still being unregulated. If one exchange got taken down first, it would likely be btct if you've been following the relevant threads.

The fees on BitFunder are there to presumably pay for legal expenses.
