I really like TribalDex and use it quite often now. Lots of really cool features and especially since it is truely decentralized having block-producers (witnesses). I very seldom use the other internal exchanges anymore with the exception of @blocktrades (which really is not an internal exchange technically I guess).
The fees seem very reasonable to me. I have no complaints and have never really experienced any issues with TribalDex. I really like the withrawal features of different tokens/coins like WAX, ETH and the like. Swapping via the pools (the HIVE Uniswap?) makes things very convenient as well.
As I was a little too late to vote on your post, I am tipping you with some PIMP Tokens (as is often said, every token is a 💩-token, until it is not). Great information about the happenings with Tribaldex.
I guess I will have to stay frosty. As you know, here in the northeastern part of the USA we are back down to the teens. My sister says it is not much better in the part of North Carolina where she is currently. Pennsylvania winters, got to love it!
