Convinced mom to DCA

Parents are both 55 with no concept of investing. They've only started contributing to their IRAs in the last couple of years and have worked their entire lives with no investments for retirement. They're basically betting their retirement on social security, and me. I started buying BTC a couple of years ago when I started working and have recently convinced mom to DCA a couple hundred every month. Not much but it's a start. Dad wouldn't buy. I come from a working class family where my parents and the generations before them lived in poverty. I've also spent years of my life living in poverty. Things have gotten a little better over the last few years but to lift my family out of our social class will take more than just working hard at a job. Sometimes I feel helpless watching them living their lives willfully deceived by the fiat system but bitcoin gives me hope.
