Don't believe on UK based company because they can be a fake one like most of the HYIP used them

Also looks like the owner of Listex have bought an email list from some scammer and sending bullshit emails promoting their ICO/exchange to random peoples https://bitcointalk.org/index.php?action=trust;u=2123641

I have never used them before but looks like they have intention of scamming people in short run so it is not a surprise. Avoid using new exchange and stop dreaming of making big like through binance by investing in exchange's ICO.
