It's super convenient, but sometimes a 15-hour wait is just too long for me. So, I still use other mixers, especially when they have free mixing promotions for certain cases.
As far as I know, you can increase the fees if you want to make it faster (
correct me if I'm wrong). But if you don't want to increase the fees, you just need to wait for about 15 hours. I think it won't be a big problem if you don't hurry to sell your Bitcoin. I personally rarely use mixer to send my Bitcoin but whenever I want it, I only use Coinomize. I don't see a problem with Coinomize, so we don't need other mixers.
I use mixers once a month to sell BTC for fiat. How about you? Do you use mixers regularly? Are you always sticking with Coinomize.biz?
I rarely use mixers. Sure, I only use Coinomize if I want to use mixer services.
