Welcome.

No, that makes you very wrong, because you're comparing finity with divisibility. If you pictured bitcoins as actual coins, there wouldn't be more than 21 million, which makes the supply limited. It doesn't matter if in the next decade we propose the Nakamotos (= 0.001 sats); Bitcoins will remain the same.

You should think about it. If gold could be caught in infinite pieces, would it make my gram infinite?
