Some people stop spending coins, when the price is too low and that is bad for the whole Bitcoin ecosystem.
You are totally correct, It would be harder for the coin to known when it is just kept hidden when the main purpose of it is to be used anyway. It is just like becoming an old coin that collectors could buy in later times, but I guess not because there are no marks on each of the coin. Some how people who are Bitcoin enthusiasts resiliently drive the ones that are sad when bitcoin price is down, post some posivitive vibes about how would BTC is going to moon again, and so far I kinda like those guys, there tons of social media groups that I joined with positive thinking and never had been wavered whatever comes and they just kept buying Bitcoin. They somehow drag us to buy even more and also been encourage, so we are reluctant somehow to accept defeat in bad times.
