That's great, it's been a while since we've seen Bingzi~

While trading is good, based on past experience, when a new protocol has both an official token and a community-driven token, it might be safer to find ways to acquire the official token. If this privacy protocol becomes successful, not to mention anything else, its official token is definitely going to rise, which is a good thing.
Of course, if you're playing for the short term, it's still more comfortable to trade the community's token.
