I decided not to buy etherium because the developers have failed to checkmate, evaluate and verify the authenticity and veracity of the project managers using its blockchain to run various ICO.This has resulted in high instability on the future and price of etherium.In order words,there is also tendency that some genuine project managers using etherium blockchain might build their own blockchain, and once this happen ,the liquidity of etherium will be distorted.
However, I observed that etherium developers have not shown the total supply of etherium, and this is one the reasons I decided not to buy etherium because not showing the total supply of etherium means more coins could be created,and this is not a welcome development for long term investors.
I can see your point mentioning about the total supply of ethereum. As supporter and as an investor we always check on the important info and details of the project and we never miss to look at the total supply because it could give us the confidence of investing knowing that very essential information and I also wonder why ethereum do not divulge about that matter.
