yeah you are right that it still good time to buy bitcoin because bitcoin will be more increasing its price so its really good time to buy bitcoin and then hold it for year or tow year and then you can get a huge profit from bitcoin .
In life I believe anytime you buy bitcoins is the best time, because you know the bitcoins will soon spread among more and more people and once that happens the value of each bit of bitcoins will be gold equivalent. Just try to buy bitcoin as low as possible and try to resist yourself from selling since you will earn much more in future.
And that's of course a speculation. It might look that way now, but as with any kind of investment, there is no way to tell what happens tomorrow, much less what happens in five years. Big finance might have swiped out bitcoin and replaced it with their own standard blockchain at that time. Always be sure to only invest the amount you are prepared to lose!
