I am interested in investing in Stratis but I don't understand the purpose of the tokens. They don't seem to be used like ethereum gas or currency so where is the demand for them? Is their only purpose to secure the masternodes?
Strat token is also needed for upcoming ICO platform, same way you need to participate in ICO through ETH you need STRAT to participate in ICO on STRATIS ICO Platform, so we can expect some serious demand in tokens soon 
Okay, thanks for that explanation, I have decided to invest. Indeed, if Stratis-based ICOs become popular there will be a huge demand for tokens.

companies will need to purchase and lock up stratis tokens to run a side chain
Another good use case, thank you.
