It is worth to me, not only because i use it often to making my deals and trades online, but also because i think it's having good potential and shining future, we expect also it's price will get stable soon.
Price stability will be temporary in bitcoins, you cannot expect that forever in bitcoins and if it gets stable then it won't allow people to make profits that they are making at a moment with price fluctuations.
But, after bitcoin attains some very high prices there would be some possibilities for stable price still we can not ignore the halving event every ~4 years.
So, basically bitcoin is here to have very huge prices, in the journey toward higher price levels some fluctuations are most common. But making use of these fluctuations will help us to consider bitcoin more worth to us for sure.
yeah i think altcoins should get stable prices if there actually would be way more people using it
