2) Should it be considered in the future to increase the decimal points to the right? Effectively 10x all the satoshi in existence (the equivalent of 1 decimal point increase)
This is not really an increase in supply as all balances AND past transactions would see that increase. What it would do is add precision to allow for even smaller transfers of value and maybe more granularity in fees
I do not think that is ever going to be necessary, even if at some point we got an equivalence of 1 dollar for one satoshi it is very likely that at that time the dollar would have gone through hyperinflation which means the dollar will not buy anything and the satoshi will still be small enough and will allow enough granularity to our transactions.
However if it is ever needed the developers will add it as if they can pull off something like the lightning network then adding just a few decimals to the right should be something incredibly easy for them.
