Investing in value when something has no value is a high-risk investment and is considered a risk if you do not have a convincing reason to invest and you diversify your investments so that the loss of that investment does not affect your investment portfolio, but capital is cowardly and nothing will take such a bold risk.
To simplify it for you, the price of Monero is 151.52EUR, so if you have 50,000 Euros, will you invest in Monero, After all the bad news about that CEXs have removed it and that the countries do not want it? This is exactly what was happening to Bitcoin in 2013, everyone thought it was a currency of the dark web and you had to do something illegal to buy it.
When a new technology is born, it faces with many uncertainties, challenges to survive and it is hard to believe that it will grow up and exist with time.
Especially Bitcoin relates to finance so it is attacked more by news, fud and even with higher levels of attack, governmental attacks. It is hard to control your minds if in 2013, you woke up and read news like China wanted to ban Bitcoin mining next month. Nowadays we know it is fud as it has been used many times and Bitcoin was not die, Bitcoin mining still exists in China but in 2013, such fud would like a bomb to kill mentally weak investors.
Many top altcoins were dead and if I did similar investment like Dan, I already lost money in those top dead altcoins.
