There are different reason about their zero liquidity, such as
1. Chaincase only available for iOS device and still on TestFlight/beta phase. As for sakewallet, i can't even find their website.
2. Both of them has very little publication. I just heard existence of sakewallet from your posts.
3. Wasabi Wallet only use their own CJ server. If the software force user to choose CJ server which show several alternative, i expect few user would choose different CJ server.
1. Chaincase app coordinator is available for all platforms where Wasabi Wallet can run, or do you mean iOS users, in general, aren't that interested in making CounJoin transactions? As for sakewallet's website, I only found this:
What i meant is very few people use Chaincase and even fewer people interested to make CoinJoin (probably due to 0 liquidity). sakewallet looks like is dead since their last tweet was on March 17.
2. Again, this only indicates that very few are really interested in finding alternatives to default coordinator.
Fair point, but how many Wasabi Wallet user know there's option to change coordinator?
