Looking at CMC's trading volume for the past year, it looks like the coin has went days, or sometimes weeks without barely any volume. Not making light of this, as I'm sure there are some people who lost money, but let this be a lesson to stay away from this type of stablecoins. You would think after what happened with Luna, people would steer away from those already.
This is an Algorithmic stablecoin, isn't it? Not backed by real fiat or gold, DAI is a stablecoin backed by crypto assets while Balance coin relies solely on demand and supply.
At least that's what I read in the article.
I do not know why there are some people who believe in this obscure stablecoin, like you said the volume in February of this year aja $0 no activity whatsoever.
Yes, according to Coinmarketcap, it is an algorithmetic stable coin

Luna stable coin (UST) will not teach many people a lesson which was also an algorithmetic stable coin that people also suspected will depeg in the past and it depegged.
Such stable coins supposed not to exist anymore, but crypto is just very bad in some aspects.
