Ionomy is a notably excellent exchange because of their clarity and honesty.
I would recommend them to both users and teams listing coins without reservation. Their direct approach, friendliness, and candor stand out.
I can't actually say much more because it is a very plain, simple exchange that works well supported and built by a great team.
Which means nothing, even if it were true. There is no lack of exchanges.
And there is nothing "honest" about the unfulfilled promises they've been feeding their bagholders for ~5 years now. Luckily they're sufficiently incompetent in promoting their garbage so chances of anyone new getting scammed by them are very low.
