Fro BTC retirement plan, check this:

https://apyharvest.com/save-crypto/

I am already using their R2B plan - "Plan R2B: start 1 BTC, add 0.05 BTC each month @ APY 6.56%" , "R: Crypto retirement plans . Term lengths 5, 10 and 20 years. Compounding DAILY. Stick to the plan for 180 days, and earn additional 0.3% more APY% per 180 days cycle."

It has been already few months. I love their email reporting and personal crypto banker.

Big advantage for me was also that i can open accounts to all my family members if i want. Interest I earn compound daily, and nothing is locked - if needed , I can withdraw ALL my crypto assets from there at any time - no penalty, no fees.
