Why there was a delay in publishing the coin to bitcointalk. I think the coin was mined by dev before publishing it.
Is that same as premine?

This is not premine. I wrote about this coin on November 29, but many abandoned it due to difficulties with installing a wallet.
Now you need to take risks for profit and be more active in the mining communities.
