My bid is withdrawn.
It is not possible to withdraw your bid, but it is also not necessary. 1 BTC per 1% of profit from an ASIC is highly undervalued.
is this still opened?
It will be open for *at least* 12 days, but may be ended sooner (see OP).
Will shares be transferable after the auction ends? (ie can I sell these in 1 month to another user)
Don't treat this like a business IPO. This is a personal arrangement for multiples of 1% of the ASIC's earnings. If you ask me to change the payment address at a later date, and that address happens to be someone who paid you money, I don't see why I couldn't oblige, and equally so, if you both agreed to have that new party be in control of that % in the future, I wouldn't stop you. I am not going to issue a stock certificate or anything silly like that though.
