I think its a great time to buy now but when is a good time to sell (if you have any idea please share)
No doubt that we can buy bitcoin any time and will.never results into loss , if we can hold for long term .
But here we need to get Profit in less time , We should buy bitcoin when the chances of increasing the price are high in the incoming days and then sell when it get price achieve According to the prediction .
Second thing here we can see that , we should buy when negative news / rumours going on the social media and making the bitcoin price down ( simple example of ban of ICOs exchange in China , that was the perfect time to buy bitcoin ).
And sell the bitcoin when good news running about the bitcoin Because at that time that was the sharp price for that movement in the market .
