Many of us panic to see the dumped happen in 2017-2018, and in the next year, the price slowly gets down and makes many people leave the crypto for a while. The downtrend that happens to bitcoin slowly changes this year and the price can back to increase and even recorded a new ATH this year. So this downtrend is just another moment for people to buy bitcoin at a low price than yesterday. If you want to use this moment, you can start to buy or wait for more to see the other lower price.
Like many other people, I am also assuming that we are in the middle of bull run; so there will be no meaning of getting panic on seeing prices falling down. I checked for the reason for yesterday's downfall, and it seemed usual market correction due to some people were profit booking or got liquidated in leveraged markets. So, just to making use of this collection will definitely will not disappoint any long-term holder.
