I did this exact thing. I wanted exposure and saw nostr:npub15dqlghlewk84wz3pkqqvzl2w2w36f97g89ljds8x6c094nlu02vqjllm5m as the best way for my Roth. My investment co wouldn’t let me invest, so I moved a chunk to a self managed account and bought. It was ugly for a while and wish I’d have bought more at 137…but hey it’s always good to wish you had more. I know straight BTC is best, but as you said, it’s not easy for everyone to convert retirement funds into BTC.
