Unclear situation regarding token and their benefits

Hi!

Thank's for the quite detailed white paper. However, to me it is not yet clear how the token situation behaves. Are there different kind of tokens? One for application operators, one for node operators, one for block produces and voters? What is the incentive to operate an EOS computation node? Which token to use for voting? When voting for one of the 21 block produces, will I as a voter be receive a share of the earned tokens of block producers? Most likely you will finance EOS through investores buying your tokens, so what's the business case for these investors? Being one of the 20 most voted block producers or the single random token holder is very unlikely and if that is really necessary to receive RoI, I'd consider EoS to be a scam.

Maybe you could bring light into the situation and describe which tokens exist, what they are good for and what the advantages/disadvantages of them are in a more clear and detailed way. Because I really like the idea behind EoS and would like to support it - once I understand the business model =)

with best regards,
Miek
