I was one of those people who considered P2P lending is a disaster prone thing to consider and I cringed at the existence of https://en.wikipedia.org/wiki/Lending_Club I'm not too big on SALT. I haven't done too much research into it. But I know you use your crypto as collateral. It's loans backed by assets. There is high chance that the loan may end up paying for itself.

All this is 100% sustainable and actually adds value to the world we live in. At least in theory it does.

Sure you can say Bitconnect is a pyramid and sure you can say @craig-grant is near the top. The difference is at least we see regular people working their way to the top of these pyramids with no bias against nationality, gender, political views, etc.

The crypto bank has it's promoters who bring in new lenders such as @craig-grant.

That's the definition of ponzi.

My opinion is the Ponzi Scheme is the bank charging us to lend them money!

Banks that doesn't charge for lending are ponzi. That's what wrong with the banking sector. The interest rate is non-existent or even negative. This is clearly punishing the savers.
