You have an option with Fidelity to trade the stock GBTC (Bitcoin Investment Trust). Over Christmas, I was able to make a nice profit into my ROTH IRA holding GBTC over the four day holiday weekend. That being said, the stock trades at a high premium and a long term hold might not be the best option. One thing to note, earlier this year the stock split making it a lot more affordable for the average person to buy. Prior to the split, the stock was trading at $1600-$2200 a share.
