This sub gets a lot of hate for giving "Terrible" advice. Here's some great advice that I've gotten from this sub in just the last year:

Buy and Hold: Pretty straight-forward. You won't become a millionaire overnight. You have to wait.

You can't time the market: Nobody knows when the top or bottom is in.

Do Your Own Research: Don't take advice from random people from the internet. That guy who just posted that long and detailed DD could be 12.

The Majority of your Crypto-Currency Portfolio should be in BTC and ETH: Two of the "Safest" Crypro-Currencies to own with a great track record that are standing the Test of Time.

Don't Invest More Than You Can Afford to Lose: For every person who leveraged their life savings into Dogecoin and became a millionaire, there's a thousand people who lost it all - Don't fall for Survivorship Bias.

You Shouldn't Invest Everything into Crypto-Currencies: A retirement account and / or a well diversified portfolio of stocks, bonds, property and precious metals should be a necessity for everybody in Crypto-Currency.

Most Youtubers and Influencers Don't Care About You: They make money off of your clicks and if they think that the bear market is around the corner, they will dump before telling you and not afterwards. A lot of them pump and dump coins as well.

Nobody Knows Shit About Fuck: Probably the most important piece of advice on this list. The market is irrational and doesn't make sense a lot of the time especially in the short-term. Sometimes it's a case of Buy the Hype, Sell the News and sometimes it isn't. Sometimes it shouldn't go any lower or higher, but it just does against all the odds. Be careful out there.
