I want to find out why everybody wants to invest in altcoins, what I want to ask is, how much money did you get from altcoins so far?
Here the most important thing is your risk-reward ratio. You may invest in some illiquid token, but have trust in that and the price may appreciate really a lot. However, you can invest in more stable altcoin and have fewer profits on it. Higher the risk, higher the potential reward and higher probability to lose it all.
