If I understand it, when in SHARES the same number or more than the current difficulty appears, I would have 1 chance of finding a block, is that correct?
No, you chances are the same with every share, you never get "closer" by doing more shares. If your shares = the current difficulty, your overall chance of finding a block works out to approximately 63%.
And the SHARES monero increases with each valid action of the miners, right?
No idea what shitcoins have anything to do with this here.
the amount I wanted to say, the translator sometimes fails....
