You’re doing the right thing by thinking through your security and setup now, rather than later (or god forbid not at all). I also can respect wanting to keep it in the family - I do the same, and I think part of life is learning to trust some of the people you care about with some level of responsibility.
I wish you all the best in your journey and hope you find a good setup which works well for you. There are lots of good resources to help you (podcasts featuring #[5], #[6], #[7] have huge amounts of useful and valuable information) and tools will only continue to improve into the future. Safe stacking! ⚡️
