Just a thought when looking at the candle chart. I believe it would be possible when total funds are huge enough.
There is no currency that is completely stable and that means we should not expect absolutely stability in cryptocurrencies and bitcoin's pricing. I come to understand of recent that USD from inception has not be stable and it has been going against or for any other coins in pricing. I believe that bitcoin in some days to come we would have some stability and 2019 the volatility is going to resume again.
The thing is, the higher the price, the harder it is to move it as more people are involved and it needs more funds. And it can be seen with bitcoin price because throughout the history the first pumps led to higher percentage increases in price than the more recent ones. From this a conclusion can be drawn that bitcoin will become more and more stable in the future and end up being as stable as, for example, dollar.
