Be informed first hand that presently Instant Bitex exchange which is headquartered in United Kingdom and released in 2018 has no liquidity, as it is also being discovered via its website link that it is no more a cryptocurrency exchange but now a site comparing Bitcoin exchanges. So I kindly advise you to exercise caution and be guided with guarded.
Instant Bitex charges 0.10% for both taker and maker as trading fee which is quiet competitive and it charges you 0.0005btc as withdrawal fee which is quiet enormously competitive compared to the industry's average.
Instant Bitex supports twenty cryptos and doesn't accept fiat deposit except cryptos deposit so for that reason new investors can not trade on it.
