Something on this website is really strange and suspicious .. Their support is also very strange.
I will write how it ends, but I also advise everyone to stay away from this exchange.
Seems that you will be surprising with more strangeness from Vindax.
This is a scam exchange. A lot of accusations against it had been made here in our forum. This a
full list made by google.
I think there will be more reports from users as long as Vindax is nicely presented in coinmarketcap. Some thinks that Vindax reports fake volumes. I would never suggest using this exchange at any costs; in one of the accusations, i got understand that Vindax set a funny rule to withdraw, in addition to the high fee, you can't set an amount more than two digits
