Something I noticed is I see a lot of people saying something like this: "I invested in this coin, it looks good." It's a very common phrase when someone gives a recommendation around here.

It's telling when someone says "that one looks good" instead of saying "I know that one is good"

It like when you ask your friend a question and they say "I think so" instead of "I know so". It's away of distancing yourself from your answer to mitigate any damage in case you're wrong.

It also strikes me strange when someone's got a portfolio with 10 or more different cryptos, I just think that's plain wrong. Ideally you should have up to 3 cryptos (personal opinion), and I've explained why in this thread https://bitcointalk.org/index.php?topic=3627234.0 but the takeaway is that cryptos are risky business. It's not good to expose yourself more than you have to. It's like staying in the casino longer than you need to.

If you were offering a sniper rifle or a shotgun to someone, the person with his/her eyes wide open would choose the sniper rifle. The person with their eyes closed would choose a shotgun.
