So do you all like... UNDERSTAND crypto?

Many posts make it seem as if many people have a very profound understanding of crypto concepts and what event will affect it how and every time I try to really understand crypto I am quite discouraged by the amounts of information available and the complexity of it. Also the info is super different from one coin to the next. I'm not an uneducated person, I have a degree in econ, and I still struggle.

I have been investing for a while (a little over a year) and I've made some really decent returns, enough at least to put my schwab account to shame. However I have NO UNDERSTANDING of anything you smart people talk about. I see a coin go up, I take a mental note, I see it go down - I buy, it goes back up - I sell. I hold onto Bitcoin and Etherium though (I don't even know why everyone misspells hold to hodl lol).

I'm concerned to admit how little I understand crypto considering the amount of money I have tied up in it and I am just trying to hear some honest feedback - is it just me? Or is everyone on here super crypto savvy and knows which coin is best to invest in?

Please don't be harsh, we are all here trying to make a buck or two :)
