Interesting timing on this post TraderJoe. I started my ENZC position in a traditional IRA I set up years ago and had a few thousand dollars in. Once I realized what I had with ENZC and a couple of others, I started the process of converting it to a Roth. It is ongoing as we speak. Takes 1-3 biz days w TD.
I'll owe the taxes on the principle I put in a few years ago plus gains up to the date of transfer of shares. Then any gains from then on is tax free.
If the account skyrockets it will be a brilliant move. If it tanks, I will have paid taxes on money I never received. :)
