Been researching on how to calculate ROI. Will this be a long or short term inv? What will happen to tokens after being used in parks? Though its good to know that you have already establish the necessary facilities needed it means shorter period of waiting.
Short term investments means that you will sell it within short period of time which is usually operating period. I believe building huge parks is for long term purpose, as to the used token I think I read somewhere that it will be consumed and will not go back to circulation.
