I have almost there same story. Got rekt in shitcoins in 17/18. Gave up. Came back early 21 and became a maxi in less than 6 months. Wish I got it the first time, but I'm definitely not too late.

At some point I really realized what was going on and it was like I got hit by a train. I can't remember exactly when but same, within months of really focusing and trying to find good content and voices it was over. The proverbial lightbulb went on.
Yeah I don't think the content was available back in 17/18 anyway or there was too much noise in the way to find it. I kind of knew the technology was a major innovation, but didn't really understand how exactly, so it was easy to get distracted by all the bullshit. Once you zero in on it though there's no getting distracted anymore. The laser eyes are a really apt meme for Bitcoiners 😂
Andreas Antonopoulos really helped me sort it originally, but yeah, it was too amorphous to me then. Once I really understood the block size thing it clicked I think. That may have been my real hold up, the scaling.
That is still on my mind, but without a fair underlying distributed robust network it wouldn't matter. So I think that was my last realization. And now here, playing with all the lighting implementations and going back on chain and all that, has been a whole new perspective.
