I understand the Bitcoin Price was a bit stable as at the time the topic was created. Volatility is what makes Cryptocurrency market the best. Stability in the price of bitcoin would not yield the investors or traders any profit . The general nature of Cryptocurrencies is Volatile , that is what brings profitability. Experienced traders buys at deep and sell when the price improves. Bitcoin will never be a stable Coin . The Volatility helps the market alive and breathing.
There are times when bitcoin price is stable. Last year bitcoin remain stable between 6000 - 7000$ for few months. This year at the start bitcoin remain stable between 3500 - 4000$ for about 2 months. But there are times when bitcoin is very unstable and it moves 200- 500$ up and down daily.
I think it is impossible for bitcoin to become stable because there is no one who can control and make bitcoin value stable. This is one drawback of decentralized currency.
