Im wondering how much salpay reafy did collected during the token sale? Is that too low for them not to be able to take salpay tokens to be listed on a lot better exchange?

Salpay is also a singapore based company so they are also supporting a startup exchange based in singapore.
Based on the stats on the website they raised more or less 12 Million USD.
Yes, maybe because of that they listed in Bitafex exchange and Sal pay is based payroll activity for generating pay slip and remittance. They raised enough money for developing the product and make the partnership with the companies by giving their software.
