The booming cryptocurrency sector’s complaints that Washington has gone too far in cracking down on its unregulated products are getting tested in a key lawsuit targeting Ripple Labs and its digital coin, XRP.

The lawsuit, which the Securities and Exchange Commission filed in the waning days of the Trump administration, faces several hurdles in the coming months. A Manhattan federal judge has been asked to decide, for instance, whether Ripple can argue regulators should have clearly announced which digital assets they oversee, rather than using enforcement actions to bring the industry to heel.
