You dont even need to read the whitepaper, the 20% apy would make you curious where does the money come from. That made me not touch terra back but i hope the companies under it recover from this shit show.
The recovery may be gradual, but not in the near future because the decline experienced by Terra Luna was the worst of all the altcoins on the market.
So hoping to recover from Terra Luna is not wrong and also a very natural thing even though some people are starting to doubt about Terra Luna for now.
