Are you considering creating an ICO/STO?
You need to have a KYC/AML process if you don't want to have legal issues. Also in 2018, only 58% of the ICOs reached the soft cap. A KYC/AML process gives trust to investors.
CheapKYC.net is the cheapest identity verification provider. The cost is less than $0.5 and there is a $4000 flat-rate option available for small-medium size ICOs.
