Armin is correct and it's scary that so many people are getting upset about this. Most of the people yelling "HODL" have no idea how to trade, what a target is or how to set a stop loss.

What Armin is talking about is basic risk management, everyone should have a basic risk management plan when they put money intro crypto.

You have to realize that most people "holding" have no idea what they are doing, they are not investing into a technology, they bought a coin because they thought it would make them money.
