The creation/redemption process is intended for market makers known as Authorized Participants (APs) to arbitrage differences in the ETF price and the underlying price. While, yes, you can sell bitcoins to the trust in exchange for shares of the ETF, you would then need to sell those ETF shares in the market. So in other words, you would only have liquidity if there were demand for the ETF. It's possible that there will be more demand for the ETF than for bitcoins simply because ETFs are more accessible.
