Bitcoin will be more popular if the price is stable. More will choose bitcoin as an investment.
Because bitcoin is a digital currency that is very easy to use.
I dont think so that bitcoin would be still popular when it comes to investment because we do know we are earning profits when the price isnt stable which we can see as of now. Bitcoin would remain volatile and it cant really be chance since theres always a tug of war between sellers and buyers or between demand and supply. It might be a good thing for those merchants who would accept bitcoin because they know price wont really move anymore.
I agree with you, Bitcoin is an ideal investment and bring the most profit now because the instability of prices, so if the price of bitcoin becomes stable, we will not make profits, that also means we will need to look for new investments. Really want the price of bitcoin stable is not possible, whales will never let that happen, they will always find ways to create instability to make more money with bitcoin.
