My answer is both yes and no. Yes because the value of bitcoins are still rising even if the price are very expensive in the market so if you buy bitcoins  in the price today then the price tomorrow will rise again your money also rises as easy as that. By just sleeping in your house your money can grow. But it is also a no because the value of the bitcoins are too much high so what will happen if you buy for a very expensive value then after a month the price falls almost a half of it. What will happen to you is your money will also cut into half in that easily. We need to think wisely.
