Retired on Bitcoin

I have been retired and online over 20 years and it is becoming more obvious every year that Social Security only goes so far, but Bitcoin can stretch that a lot. Yesterday I tried a website called Bitrefill.com and used my Bitcoin to buy a $50 Amazon Gift Card to order a LED webcam light so I can make better videos and did not need to tough my Social Security income. Have you found some other good ways to stretch your retirement?
