Do you think that the price of a single Satoshi will be something like $1 one day? Or even more than that? Will there be fractions of Satoshis in the future like mSatoshis (Milli Satoshi)?
If yes, we should fight for every single Satoshi now as long as the price is relatively low. Use faucets, trade, buy, mine and hold them until you are rich. It's too late now to get whole bitcoins (too expensive) but some thousands of Satoshis here and there could be a lot of money in the future.
I am not sure about that, bitcoin could reach fantastic price but we don't know for sure, how much it will be.
But, there will be no milli sats, no fraction anymore as the nodes written that way, unless there will be another hard fork to add another digit.
Bitcoin price is expensive right now, but consider as cheap if bitcoin reach $10,000 or even $20,000.
Every sats is precious, as long as you can get it, make efforts to do it because bitcoin still on the beginning of development.
