I don't think everyone is, but some people complain about the decline in the price of bitcoin, one reason is because the person must have suffered a loss from the decline in the price of bitcoin.
if someone doesn't suffer a loss from the current decline in bitcoin prices, surely he won't complain.
there will be people who complain about the price of bitcoin, especially those who have bought at high prices. well, for now it may be redundant, because the decline in 2018 is so fast. hopefully this year it will decrease, or not.
