Terrible news for XRP and Ripple but nobody can be surprised by this. Next up we may see the delisting of some stable coins given the SEC's advice about establishing a nexus in the US. I'm not sure how this will work for a decentralized coin like maker / dai, so perhaps this is the end for them. However, this seems consistent with other regulation since they operate like an autonomous fx swap fund.

I’m surprised, because I don’t see how it contributes to the market.

This provides clarity on what constitutes a security. The SEC have been telegraphing this move for several years, ever since the crackdowns on ICOs and STOs. Bitstamp said they would delist XRP several days ago so coinbase are hardly unique in their response to the SEC's announcement.

Bitstamp isnt delisting XRP. Just halting XRP trading for US customers.

There can be no doubt that a mathematic - rather than collateralized - solution to stablecoins is the nonviolent solution.

[pjkundert]

How about both collateralized and mathematical?

If the platform supports programmatic proportional issuance and withdrawal (vs. mint and burn), vs. market-priced collateral, then negative-feedback loop controlled inflation/deflation can be implemented...

Well, in that case, I suppose it depends on the asset being collateralized, and what oracle is the input for the programmatic issuance.

If the collateral can be seized in an act of violence (as opposed to being custodied on a smart contract), and the math is unable to protect the asset, then I think it's strictly a collateral solution and not a mathematical one.
