I'll admit I'm not expert in mining. I know very little about it, in fact. What I'm wondering is what would happen if bitcoin's price reached a level that was so insane that 1 satoshi was something like $5 or even higher. Would that not screw up the entire bitcoin system? There would be no way to send small amounts of bitcoin or very exact amounts, much less pay a fee to the miners. Am I missing something in that hypothetical case other than the fact that 1 satoshi will probably never be worth that much?
I have read about this somewhere (I forgot where). It's mentioned that Satoshi can be divided to smaller units when it reach expensive price for each Satoshi. It can be done through consensus. Theoretically possible but no need for now.
yes you are right when the fees of transaction is very low then it will be more helpful and useful for lots of people to get the extra profit for their mining and the investment definitely a good chance to implement and the possibility of people to increase input field is also there.
I'm sorry, I don't really understand what you are trying to say.
