= Collapse of Terra-Luna

= In May 2022, the stablecoin TerraUSD fell to US$0.10. This was supposed to be pegged to the US dollar via a complex algorithmic relationship with its support coin Luna. The loss of the peg resulted in Luna falling to almost zero, down from its high of $119.51. The collapse wiped out $45billion of total current value in a week. On 25 May, a proposal was approved to reissue a new Luna cryptocurrency and to decouple from and abandon the devalued UST stablecoin. The new Luna coin lost value in the opening days of being listed on exchanges. In the wake of Terra-Luna's collapse, another algorithmic stablecoin, DEI, lost its peg to the dollar and started to collapse. Kwon Do-hyung, the founder of Terra-Luna, is wanted by
