Bitcoin is mainly adopted for its volatility and not for liquidity.When bitcoin price starts remaining stable means, that bitcoin is adopted by people in a wide range, so that no one can affect its price by pumping and dumping.Traders can gain profits only if bitcoin price is not stable and is volatile.They benefit by trading it against US dollars.I think, if bitcoin price remains stable, it would be dumped for price to fall..If bitcoin had a stable price, then its adoption would fall.
It is true, because right now we are having more number of bitcoin investors than bitcoin users. This will alone will emphasize why people are getting into bitcoin and what would have happened if bitcoin had a stable prices.
The fluctuating and investment opportunity of bitcoin attracts more people to invest into bitcoin, they are probably just investors right now, but surely they will turn into real adopters when they realise the advantages of bitcoin.
