One golden rule for me especially in investing in new projects.
Don't let your experiences get to your head thinking you are a pro at it. Always try to be a newbie so that you will try to question everything about them.
We love asking questions back when we don't know anything yet, better to be in that POV again so you will not be wasting money.
Skeptical.
The experience only made you stronger but it doesn't mean you became a master of cryptocurrencies.
