Actually we can not really say the exact time when the bear market season will be over, it will largely depends on the factors that makes this downfall of price value occured, if those factors that make this fall settle then the time of the greenish will soar in that certain time of the market.
Yeah you are right nobody can say anything about the coming situation, but we should not worry about the current situation. Ups and downs are parts of business and crypto investment is also a business. I hope that the price will grow again and we will make good profit in the near future. This year is not good for bitcoin so far but hope next year will be good.
