So first of all, you're not late to the game.

Think about it. If you came to the party at $1k, knowing that a year before bitcoin was $100 and a year before $1, you'd think it's done growing and you're late.
3 years later it would be $20k and you'd probably think you're late, but ahead there was 60k, at which point people like you were saying they're late, not knowing that there's 120k ahead of them.

The other thing is considering yourself non-tech. Are you able to use a computer? Do you have a smartphone? If you do, you're capable of holding your own bitcoin.
Of course there are real dinosaurs out there, people who barely know how to operate a TV remote, but I'm sure you're not one of them.
