I didn’t notice big panic among the crypto believers. For instance, Roger Ver also known as “Bitcoin Jesus” is very bullish about the crypto market in a long-term (https://cointelegraph.com/news/roger-ver-sidelines-bitcoin-cash-war-to-present-crypto-bull-case?utm_source=telegram0&utm_medium=social). Yes, the bearish market is more durable than it was expected to be. But as you said crypto is unpredictable, that’s why it won’t behave similar trend like last year or two years ago. It’s not the biggest drop of bitcoin if we take a look at its history chart. So, there is nothing to worry about at all. On the contrary, there is only one way left - to rise in price.   

it is really painful that those who had so much believe in bitcoin began to panic just because bitcoin fell in price. we should hodl own coins and believe in the whole bitcoin ideology. Most persons invested in bitcoin because they hope to make a fortune but those of us who invested because we believe in the whole bitcoin ideolgy will hodl and wait for bitcoin price to normalize
