Here is an interesting idea...

GBTC is currently trading with about 25% premium to its NAV.

That means that at some point prices will fall by roughly 25%, even if the price of the underlying assets don't budge.

In this case those underlying assets are bitcoins.

The play is to long bitcoin, and short the same amount of GBTC.

You should capture that spread over time.

What do you think?
