If you allow me… And im not criticizing your choices here. Your dad is not against bitcoin, He’s disappointed you left your shared business probably. If it was over racing cars somewhere else, he would be mentioning that instead of bitcoin. Give him a chance. Bitcoin doesn’t have to consume your life. You can buy whenever your fiat job allows you. Having a son working on a small company thats yours is probably the dream of many dads. He wants a team buddy. Not sure about your age, but i guess you have time to dedicate to btc. Your dad might not have so much to enjoy you. My 2 sats.. Hang on there!
