Not everyone but maybe 70% to 85% of all the investors and holders. Why I said that because there are many professional traders and brokers around and they might have read the outcome of cryptocurrencies this year and sold all of their coins before the crash happened. They might also lost some but I'm sure that their gains still dominates.
Bear market is always an opportunity for professional traders who simply have the swing strategy style of trading. It may be a bit hard for day traders to trade a volatile bear market which is why so many day traders rather prefer to stay clear the market during some periods than trying to trade the market at that point in time.
The bad thing however, is that a lot of people in the space trade with little or no knowledge, and for a bear market, that would be the worst for them to ever trade.
Most of the people really lose their money when the market is down. You can easily avoid these losses if you stop trading for some time, hold your cryptos and wait.
