As it happens, $1 invested monthly in a conservative portfolio with 6% annualized gains results in just under $1,000 after 30 years. So put aside $80/mo from your monthly budget into an investment account, and use the full balance to pre-pay membership when your term insurance is up.
a conservative portfolio with 6% annualized gains
Ain't no such thing at the moment.
Not to mention that you should distinguish gains in nominal terms and gains in real terms.
I wrote an article about the process of signing up for cryo since I couldn't find any such accounts online. If you have questions about the sign-up process, just ask.
A few months ago, I signed up for Alcor's brain-only cryopreservation. The entire process took me 11 weeks from the day I started till the day I received my medical bracelet (the thing that’ll let paramedics know that your dead body should be handled by Alcor). I paid them $90 for the application fee. From now on, every year I’ll pay $530 for Alcor membership fees, and also pay $275 for my separately purchased life insurance.
