I was around 25 when I started learning about bitcoin, and it did be interesting to let you guys know that I lost my very first bitcoins I bought to a scam ico back then in 2016 when the concept was still very young, it was a wild experience but am glad it taught me what it taught me 😁.

Well, I honestly don't believe age has any role to play, what I think has  a very big role to play is prior experience and IQ level.
Right from my younger age, I've always loved the internet and anything that has to do with internet has always catched my interest, back then, I fancy the internet more than I fancy driving sports cars, I believe this is what actually helped me in learning about bitcoin and cryptocurrencies.

Look around you, everybody wish they know what they know now earlier, it's normal and that's how life is designed to be, as we grow and acquire knowledge of certain things, we begin to wish we acquired those knowledge yesterday, because we think our lives wouldn't be the way it is now (i.e, we think our lives would be much more better) if we knew what we know now yesterday.
So universally, this kind of regret is practically common with every one, starting something today, and after you've made some progress, you begin to wish you started it earlier, it's a normal feeling.
