Im 24 when I became aware of the Bitcoin's existence, but that time im not yet interested because my mind is filled with other things. 27, when I started learning about it and 28 when I got my first earning.

Well, its a big help to fully understand crypto. Being mature enough to know the risk if you engage yourself especially I already have a family of my own. Hence im motivated to learn and embrace the opportunity thats in front of me.

No. Because regardless of a person's age as long as they can understand Bitcoin (or crypto in general) and the technology behind it, then thats enough. Because everyone can learn it if they're willing to do so. Thus even you're already old its not too late to join the ride.
