I would guess that Coinbase, as a long-standing US-based exchange that is now publicly owned and therefore subject to various (stringent? not sure if I should laugh at that or not) business regulations, would be attempting to achieve / maintain legitimacy in the least under-handed way possible given the prevailing winds are already heavily cryptocurrency-skeptical.
Clarity is what's being asked for. If the SEC deems some/all cryptocurrencies a security, then allow Coinbase (or whichever other exchanges) to file the paperwork required to exchange securities and we can all be on our way.
But, it seems that the SEC doesn't actually have any process for that to happen. The paperwork either doesn't exist or the process has a gap whereby cryptocurrency security exchange requests hit a cliff with no bridge.
As per Jesse Powell:
“The ‘This is wrong but I won’t tell you how to do it right. Want to find out if X works? Try it and see what happens.’ approach does not help the industry nor consumers. We aren’t anti-regulation but we need a clear path to operate.”[0]
"Oh man, all I had to do was fill out a form on a website and tell people that staking rewards come from staking? Wish I'd seen this video before paying a $30m fine and agreeing to permanently shut down the service in the US. How dumb do I look. Gosh."[1]
Both sides are likely being somewhat disingenuous, but the SEC, given it's role, should never, ever, fucking be disingenuous. And given it's a government department with its... severely chequered... history, then I wouldn't be betting on it having it's i's dotted and t's crossed.
Kraken and Coinbase were established in 2011 and 2012 respectively, so they've been run well enough as businesses to weather three or four cryptocurrency winters that have taken the lives of many others. In an industry with a dearth of trustworthiness[3], these two stand out from that crowd.
