Investing in bitcoin is a risk, as the value can crash tomorrow.
I'm holding too so far, I believe in what bitcoin represents, so I'm taking the risk. Don't invest more than what you can afford to lose however, but if you can, you should buy more.
Also have a look in other cryptocurrencies.
Yes. All kinds of work are at risk. You can risk holding it down. Because the price at which the market is today may not have it tomorrow. Maybe the price high may be lower. If the price is low, it may fall in losses. But do not be at your risk. Because tomorrow the price may go up too much. Then you will be benefited a lot. Those who improve lives. All those people who are improving in life are at risk. So all of us should know how to buy bitcoin by looking at the price bureaus.
