Year 2018 seems to have the most prolonged dip from what i have seen so far. Some people had serious loss along the line; some vowed never to invest in cryptocurrency again; some sold all their assets and left.
Your encounters though might seem not encouraging, but do you know that you are better of than the person that is just coming in, because of what you now know.
Let go of your mistakes, but whenever you remember them, tell yourself it is not yet over, the crypto space will still get better and you will be glad you're still in the system.
Vowed never to invest? You will see those exact people jumping back on the train when the price has reached a new all time high. They will invest during that time and when the price starts to stabilize again and reach an average price, those investors will start crying. I don't get why they whine when the price falls. They knew about the risks and still joined the market.
Don't just let go of your mistakes. Learn from it and avoid doing the same mistake again.
