A new cryptocurrency!

As a programmer, I have the gifts that are required develop software. Even though I have very little experience when it comes to the blockchain technology and cryptography, I am confident that I can quickly learn the things I don't know yet and put them into practice. Having said that, I have been thinking about creating and launching a new cryptocurrency for a while. I have a few questions from anyone who may have the answers.

A few questions

Question 1

In your opinion, what are the things that are missing in the existing cryptocurrencies? Any features you would like to have them added to the system? Any flaws you would like to have them removed?

Question 2

Is an offline and blockchain-less cryptocurrency possible? What if we had a cryptocurrency that did not depend on blockchains or the Internet? And we could make offline transfers as long as we had access to the two wallets involved in a transaction?

Question 3

How would you like the idea of mining a cryptocurrency via a pokomongo-like app? I think mining a cryptocurrency through a pokomongo-like app would bring equality in the mining process, at least to some extent.
