Well, there are a lot of issues with Vindax. I rather stay away and never using that exchange.
Safety is the main thing in the crypto business. So, it's better to use a big exchange like Binance.
It is a smart decision, we just need to go to big exchanges like Binance, Okex, Huobi ... and we will never have problems like the present. Small exchanges have too many FUDs and scams, which makes many investors lose money and lose money when using it. I personally also never use this type of exchange, too dangerous
