Advisory Service Terms

Terms pertaining to advisory engagements are market sensitive and subject to confidentiality agreements. As a rule, service fees are made up of monthly retainer fees and a final success fee; the latter usually being a fixed fee or single digit percentage of the global proceeds of the project token sale, payable on its successful completion. Whilst these revenues can be meaningful, fees are usually denominated or payable in cryptocurrencies or project tokens and are therefore often subject to the high levels of volatility witnessed in this industry.

The Directors of Coinsilium Group Limited take responsibility for this announcement.
