Every investment carries a potential risk. As such, there are various risks and potential problems with investing in Bitcoin. The cryptocurrency world is a high-risk world. Here those who have become adepts are just looking at the profit and progressing gradually. Many of those who didn't succeed are still trying, and some have turned their backs on cryptocurrencies. Because they think if they invest here or spend time here, they will only lose. It is as if they are unwilling to accept that the loss they have suffered is due to their own fault.
There is no gain without risk. In fact, risk and reward are linked especially in the crypto space. However, the big question is whether the risk is worth taking. There is no investment totally freed from risk but the risk associated with bitcoin is second to none ranging from market crash, transaction delay and of course, falling victim to hackers. I don't blame anyone when I see them turning back on cryptocurrency despite not the best choice to make. There's actually a potential gain in the long run if one can endure through the dark period.
However, I won't agree with the Op that investors should overlook all these shortcomings and focus only on the brighter side. It's good to pay attention to every bit of aspect and derive a measure to balance the situation. That doesn't sound like an investment advice because risk are not equally created.
