Do you guys think that bitcoin would increase the number of pieces of BTC in the future? I would also like to know if there is a maximum threshold for the coins.
It is possible but it will never happen. This was the reason I stopped using DOGE....
I think the problem people have is they tend to equate 1 BTC with other units such as 1 USD. So this leads to thinking along the lines that 21 million is not that many, after all even if everyone in the US were to acquire some BTC, there would not be enough for everyone to possess a full BTC.
It may be better to think of 1 BTC as something like a $1,000,000 Bond or some other form of monetary holding and the satoshi as the more common (everyday) form. I picked the $1,000,000 example since that is the value BTC would need to be for 1 satoshi to equal $0.01 or 1 cent.
I believe there was discussion early on they could always tack extra decimals places at the end if needed, but never about raising the 21 million cap.
