DO YOUR GOD DAMN RESEARCH.
Don't throw your money into ICO's or buying a coin because some guy on the internet told you to.
Be ready to lose your money. You don't know what's going to happen. The coin might skyrocket, but if it goes to 0, be ready for that. Don't put in your life's savings.
BE SMART. Use common sense. If it seems too good to be true, it is.
