Standing for “Crypto One-Stop Solution”, COSS aims to gather all the features that a cryptocurrency investor might need under a single platform. Launched in 2017, the exchange prides itself on its transparency, speed, and security. Alongside being a trading platform, COSS boasts other features such as “a platform for ICO launches and promotional trading campaigns.” Though it is based in Singapore, an exchange review reveals that the exchange has multiple ties with Romania, the biggest one being that it is a member of the country’s Chamber of Commerce and Industry. It is also a member of the Singapore Fintech Association (SFA).
