Definitely the Terra and FTX collapse takes the cake for the most impactful event in the crypto market this year. Both will go down in history and will be remembered like how the OG's experienced Mt. Gox.
I have note list with three bigger tragedy in cryptocurrency during 2022, first we still remember with Terra Luna network coin have been scam or drop price drastically, Luna having serious problem with price drop from $100 become shit coin until right now. Second bigger tragedy about FTX as two highest exchange market have been collapse and many people loss their fund after withdrawing problem close, actually FTT coins as part from FTX exchange have going dump almost the same with Luna coin.
Another fake promised with Mt.Gox exchange market never refunding with their user Bitcoin assets, having rumor they will refund all Bitcoin assets to their user trough August 2022 until end this year never have planning to refund their member Bitcoin assets.
