Help Me Understand

To be honest I have been a crypto skeptic for a long time. When I look at things like Bitcoin having a 1.8 trillion market cap I just can't make it make sense. That half of Nvidia. Larger than a lot of companies that actually produce goods and real technologies that people use on a daily basis. I don't know anyone that actually uses Bitcoin or any other crypto on a daily basis. I understand it has some "cool" technology, well to be honest I probably don't understand. I do at this point want to understand though. Where do I start? Is there a good you tube channel to watch to really try to understand all of this? I would need crypto for a 5 year old approach. I'm not very tech savvy. I grew up outside. I don't really even know how to use excel. Lol. I do feel I need to try to understand what's going on with crypto. I want to start investing however, I am hesitant because at this point it does not look like steady long term investing strategy. To me, it looks like a couple of massive bull runs with absolute nothing in between... will this change at some point? Will people ever actually use crypto on a daily basis? I do see how these technologies are the way of the future but actually trying to figure out which ones are going to be the go to tech seems impossible at this point. Bitcoin has the largest market cap but it seems like there may be newer cryptos with better tech that could actually be more usable?
