The way bitcoin price has been increasing has been alarming lately and I can say that no other currency has the amount of power that bitcoin has, I can remember vividly sometime during January ( I mean early January) bitcoin was only struggling to reach $1k but now come October, the currency is almost nearing $6k ($5600) to be precise, now I want to ask if there is a mark in which bitcoin will stop increasing or is there a mark it can't cross.
There is no price limit for Bitcoin or any other cryptocurrency. Its completely based on the free market, so its worth what people are willing to pay for it.
On thing that helps keep the price rising is that the mining gets more difficult over time. There are fewer Bitcoins mined every year and there is a limit of 21 million Bitcoins that will be mined. This makes Bitcoin deflationary while fiat currencies are inflationary.
