Found This Motivational Picture on Twitter.
This picture was clicked on March 2020. At that time, #BTC and #ETH fell more than 50%.
#Bitcoin was trading below 4,000 USDT and that was the bottom but everyone thought this is the end of crypto and most people missed the once-in-a-lifetime buying opportunity.
After that, Price went up from there and never dipped to 4K again.
I am not saying today's dip is the bottom but if you're a long-term holder, you shouldn't worry about the current price. You should just DCA your entry and check the price after a few years.
