$GBTC bit/ask orderbook useful?
The current bid/ask are placeholders, price in the first 15min/first day will be volatile. There is no certainty in price until volume develops. While I cannot predict where price will go, I do believe it is in the best interest for barry silbert to generate "buzz".
If bitcoin price close in green for the first few days. That would generate interest in his fund and bitcoin as a whole. In conclusion, anyone who is underwriting a fund wants it to be successful. They will try to market it to investors the best they can. Their success is tied to bitcoin price appreciation.
