Coinexchange.io is crypto to crypto exchange is currently down with this below message.
There is a temporary network issue with our hosting provider.
We will be back as soon as possible.
Sorry for any inconvenience caused
It looks very similar to ,what I heard about coinsmarket.com
The site is up now.
This kind of problem is usual in any exchange. It will be an alarming if the issue doesn't resolved within days or being offline for long period of time like Coinsmarket did.
People just have to wait a bit before making a speculation.
