They are all good tips, but let's not forget that oftentimes you need to make mistakes in order to understand how something works, I wish it was that easy. It's like cooking in a certain way, you have the recipe but maybe you get distracted or maybe you want to change a little the dish and it could turn out better or worse, you don't know if you don't try, cryptos are the same at the end. If you don't lose some money you will never learn, I know it may sound weird but it's the only way sometimes.
As someone else pointed out, I would avoid the meetings with people I don't know.
