Given the current market demand with the success of projects such as EOS, it's obvious consumers are interested in TX/s and not decentralization.
that is only your opinion. a great deal of people think decentralization is the main reason to even have a cryptocurrency and without it there is no point creating one.
TPS is important but only if there is demand for it. there are at least 500 altcoins with a gigantic TPS capabilities that is never used more than 10 Tx/minute.
Why not go completely centralized for maximum efficiency?
because centralized payment systems already exist. it is called PayPal, VISA, Banks,.... why should anyone use a centralized coin created by some individuals when these much more trusted systems exist?
additionally there are centralized altcoins, there is no maximum efficiency and you can see they lack popularity Because they are centralized.
you have a repeated general idea for creating a coin that will become useless.
you want to remain anonymous.
you don't provide enough information about the "idea"
and you want $100?!!!
...good luck /s
