Just saw your npub on TG tsp group and followed your npub. I used Unchained late last yr. I had an old ira from where i used to work, converted it to Roth, then moved it to unchained btc ira. Since it was already in "the system", i didnt want to pay tax on the whole thing by cashing out, so only paid tax on the earnings. The great thing is no taxes on any gains from here on (because Roth), and it has already increased in value, alot, since then.
