Cryptocurrency is a high-risk-high-income investment. This is the reason why I invest here in cryptocurrency. The risk is brought by volatility and security. Volatile because prices changes anytime and not fluctuate, it may changes drastically. Security because there are hackers everywhere.
Yeah I admit that cryptocurrency investment is highly risky and those who cannot bear loss in this field should not invest their money. If a person decides to put his money in cryptocurrency he should also prepare his mind for any situation in the market. Some times the price will go very high because of high demand or manipulation and sometimes it will collapse against expectations.
