But if you only invest YOUR money and not your FAMILY money, your family will think you didn't care about them once EOS hits the moon! :)

Does that apply to gambling (roulette)?

only what your prepared to lose just in case

Exactly, Don't invest what you are not ready to loose no matter how much profits you might see in front of you!👍
