What do you think about the appraisal of tbl.io, rxy.io, and zek.io? I have owned these domains since 2017 and now I am considering selling them.
I would recommend holding onto these domains.
In my view, the ranking of their value would be tbl.io > zek.io > rxy.io.
Personally, I believe that any three-letter .io domain with good letters is worth at least $150-250 in wholesale value.
