GBTC vs. BITO for ROTH IRA

I am a 'long' term holder of btc- 2019.

i grasp the nyknyc mantra.

now that we are over that...

in regard to adding speculation to my Roth Ira I'd like to know which is a better choice BITO or GBTC

GBTC- actually holds bitcoin which obviously is a plus. But I cannot sell calls against the shares or sell puts to buy it. GBTC also has a 2% fee per year. Usually GBTC stays below market value by a decent percent.

​

BITO- is bitcoin futures, which means the etf does not own any bitcoin. There is only a 1% fee. I can sell premium with this.

​

which for you ROTH ira would you choose?
