I don't think, there will be world war again but if there is Bitcoin will not collapse like other centralized currency,  because we experienced such challenges during the pandemic that made Bitcoin still more stand than fiat money at the moment. Many people are waiting for this bearish season to take like 2 or 3 years for them to use all their capital to purchase Bitcoin and hold until 2025 before they can sell to make a good income because by then the price of Bitcoin will reach $100k or 80k. The decreased of Bitcoin that happened early this year 2022 is for people like us to embrace the opportunity to use our monthly salary to buy and hold to have something good to achieve before the end of December.
