May I introduce to you: the hill I will die on:

1. Invest what you can afford to lose: The speaker says to only invest what you can afford to lose, because cryptocurrencies are volatile and prices can go down quickly.

2. Never trust anyone: Be skeptical of all information about crypto, even if it seems to come from a legitimate source. There are many scams in the crypto world.

3. Don't leave your crypto on exchanges: If an exchange gets hacked, you could lose all of your crypto. Instead, use a cold storage device to store your crypto offline.

4. Avoid using leverage: Leverage allows you to borrow money to invest, but it can also amplify your losses. The speaker recommends avoiding leverage altogether.

5. Take profits along the way: It's important to take profits regularly, even if you think the price of crypto will continue to rise. Don't let price predictions influence your investment decisions.
