Are there any sites which shows coins even more earlier than miningpoolstats?

Why bother? Most of them won't be listed on any exchanges anyway. How are you going to pick the lucky coin? It is impossible to guess because like I said your chances are near to zero. Instead of doing this, just buy the newly listed coins on binance and you will have the same chances of making money. (probably even better chances)

You should just mine the most profitable coin with your miners. That's how mining works. If you want to gamble later on, do what I say and buy some shitcoins. Unless you have some insider information from the exchanges, you can't win that way. (mining unlisted coins)
