We actually don't have to wait for regulators to go against privacy coins for the forum to stop accepting GRIN. The admin has already done it a few years s ago. Unfortunately, it's mainly GRIN's unpopularity that's the reason. The payment code for GRIN needed fixing but since it isn't really a popular payment option by users here, the admin didn't bother putting it back.
GRIN is probably better than thousand others in the crypto ecosystem, so there might come a time when it gains more popularity if somebody takes over the project and gets busy with development and adoption.
Yes, that's what I've meant. With mixers being heavily-scrutinized by mainstream governments, we should expect things to get worse in the long run. Privacy coins like GRIN and Monero are not immune from government prosecution. They can face de-listing from other CEXs as pressure mounts over time. A pity, because I liked GRIN a lot. It could've been a good XMR contender in the long run.
With development progress stalled (AFAIK), it should only be a matter of time before GRIN becomes a relic of the past. Same goes for BEAM. Monero seems to be the most actively-developed privacy coin to date, despite the aformentioned shortcomings. If it's de-listed from every CEX, there will be no Fiat on/off ramps except through P2P exchanges (or face-to-face). It'll be a dark future ahead for GRIN and similar coins. At least, it was "fun" while it lasted.
