GBTC/ other ways of bitcoin exposure for IRA accounts

[Jumperman4]

So today I bought 1190 shares of GBTC in my Roth IRA. I also own bitcoin but figured since I like BTC so much id increase exposure via my IRA. About 10 minutes later the flash crash of CSW's fart comes and blows down the price. NBD, I've been in bitcoin long enough to expect such blows.

My question is: How many of you use your (traditional/ roth) retirement accounts for increased Bitcoin exposure?

I grasp NYKNYC, no need to go there...again I own BTC out right as well.
