The price of Bitcoin is hitting new highs regularly now... and yet it is expected to continue rising. At what price would you stop buying?
there might be no particular time to stop buying, if there is, it would have been years back. For now the price is increasing so are there more people getting know to Bitcoin, so buying it more will be good for a time to sell and make more profit.
Everyone is speculating that price will touch $2000 in this year or even it can go beyond that so if you have a same feeling that you can buy them even now and sell them when it crosses that price so in that case you can make good profits in really very good time.
