It sounds like you're a bit of a cryptocurrency enthusiast with some hindsight regrets!

Yes, Bitcoin Cash (BCH) has maintained a relatively steady presence and following since its fork from the original Bitcoin (BTC) in 2017. It was created as a result of a hard fork, which allowed for larger block sizes and potentially faster transaction processing times.

On the other hand, Bitcoin Gold (BTG) did have some initial hype after its own fork from Bitcoin in 2017. However, it didn't quite gain the same level of traction or longevity as BCH. One possible reason is that BTG focused more on making changes to the underlying mining algorithm rather than block size or transaction speed. This might have limited its appeal and adoption.

Regarding your comment about Bitcoin (BTC) hitting $20k, you're not alone in feeling like "what if?"! The cryptocurrency market can be unpredictable, and hindsight is indeed 20/20. Who knows what would've happened if you had invested back then?

It's worth noting that the cryptocurrency space has continued to evolve since then, with new projects and innovations emerging all the time. Maybe this will be your chance to get in on the ground floor of something new!
