All my family have gone digital, when I send allowances every week, they all ask for digital transaction, ie sent to their account,they don't use cash at all. Thailand is going the same way as China, a cashless society. I left the house the other day without my wallet with paper money - I played golf, tipped the caddy etc using my phone. Blockchain makes things easier, and yes you don't understand, all transactions on the blockchain are transparent and registered for anyone to see, believing Bitcoin to be secret is what Luddites and Fuddites said years ago.
I pay my bills with a crypto.com card, and get 3% back in crypto. I pay my kid's school and university, 4 phones bills, weekly/monthly shopping at Tesco, actually pretty much everything.
