Why then should people invest in or buy a currency that can rise or fall by 20 percent in an hour or two?
Surely it's up for the people's decision and they are also aware the risk of investing in bitcoin because of its volatility in its market price. It's the only investment that can give you a double or triple ROI.
besides of the profit, people know that bitcoin has the volatility price and it is full of risk so they know what they should do in bitcoin. but the other people don't know about this and they surely become panic when the price is dropped. from a few months ago, the bitcoin price does not increase too much and it stays in under $10k without knows when its increase higher. but still, there are many new people investing their money especially at the low price like today.
