Yes investors continue to invest in crypto currency because it is profitable specially if you had buy at a lower cost. Bitcoin and other crypto currency had changed the lives of many investors but of course cryptos are also very risky investments.
The reason on why most individuals invest their resources on different tools can be primarily driven by profit. Bitcoin, to be specific, can be observed as an opportunity to yield high amounts of profit in a relatively short amount of time compared to the present investment mechanisms. Now, it is the burden of the investor in knowing when to acquire cryptocurrencies. Ideally, you would want to purchase them at a 'low price' so you could garner profit in the long-run by selling them once their price skyrockets. But again, that is the ideal situation.
That's why many investors wants to join in investing in cryptocurrency because the profit that gain from the investment,even though they have risk in investing they will continues to invest cause they know investing in cryptocurrency give them successful life in the future.
People believe in bitcoins and thats why they are still interested in investing in bitcoins and digital currency. I think the future is of the block chain technology and thats why people interest never ends.
People believing in such future can be a future threat to the price of bitcoin. Since they base their decision in the hopes of its price increasing in the market, once it shows fluctuations in price (due to its volatility), people might actually lose hope. Although there may be many factors that drive the price of cryptocurrencies in the market, saying that the main factor revolves around the 'HOPE' of people may be construed as a wrong sense of thinking.
The reason why many investors continue to invest in cryptocurrency is because of having a potential of some crypto. Even sometime they encounter a low dropped of price to it, they still continue to invest because they know they can get huge profit from it. Also those investors are really willing to invest especially now that so,e of crypto are rising especially to those have potential.
