I hardly use this exchange, but the few times I had, there was no issues, nevertheless there have not been huge news about it when compared to other exchanges so I won't be mistaken for saying it isn't that prominent, however, matters about investing in any crypto depends on the investor and what he finds attractive in that project. Therefore in my own opinion, I will say you check the features and services about the exchange, how hardworking the team is, platform developments and so on and then decide if you will invest or not.
