Crypto exists in a space that is largely a completely unregulated free market. If your crypto project can be made worthless due to some economic actors performing a free market action, then that coin never had any worth to begin with. Complaining about “attacks” post hoc is a useless activity that tries to absolve the individual of making a bad trade.
If your algorithmic stablecoin project was so flawed to the point where a bunch of people selling its stablecoin could send the entire LUNA/UST ecosystem to 0, then that coin was so flawed to be worthless from the word go.
Take responsibility for bad trades and stop trying to absolve yourself of all responsibility by inventing charades and conspiracies about how the man made you broke.
