Is investing in Stratis the same as investing in Stratis Group Ltd?

No. When you buy STRAT and treat it as an investment (as opposed to buying STRAT to use a service built on top of Stratis) you are treating the Stratis cryptocurrency as an investment. Stratis and Stratis Group Ltd are two different things. Someone who is investing in Stratis is not also investing in Stratis Group Ltd. This means that by investing in Stratis you are not given any of the rights that an investor in Stratis Group Ltd would be given. Stratis Group Ltd have never presented STRAT as an investment and they have no responsibilities to people who treat buying STRAT as an investment.
