I checked this waves site thoroughly after my first post on the same site.
Now I am curious to know how can they sell BTC and other altcoins at 20% above Binance and Gate.io
I checked all their prices and compared. Strange how they manage to do so?
This site has someone WILLING to BUY 1 BTC fo 8601 and current BTC price on Gate.io is 7860..
What does the site gain by doing this?? Waves price on TIDEX is way low by 20%.

People can Easily BUY WAVES from TIDEX through USDT and sell here.. Looks good.

(Added this later)-- Tidex wave price is $5.02 and price on waves site os $5.70 ) A clear gap of 10% at the time of this new add up)
You can Sell in FIAT on that site so you get USD.

Hope this helps. Share a Thumbs up if it did.
All the best.
