You are also saying that investors don't deal with stress - I'm sure, that all everyone who invested in crypto during ICO and sees how the token/coin price is going down straight after listing are taking Prozac immediately.
Exactly. Investing in crypto doesn't seem to be viable nowadays, especially with the high fluctuations in price. The current situation of the market, only allows a trader to make gains in the short term. Those who want to make money fast, would need to wait a pretty long time before the market recovers again. 2017 was crypto's biggest year yet, providing huge gains to early investors. I myself, have benefited largely from this trend. But having left some crypto in my wallet, has made me lose some money due to 2018's bear market. It's still today, and the bear market continues leaving many crypto investors in a panic situation.
Upon doing some research, I've found that there's no way to make money with crypto in a fast and easy manner. There's always some effort involved for you to obtain big rewards over time. Doing freelance work for Bitcoin or other cryptocurrencies seem to be the most ideal path to take nowadays. It's very rewarding if you have skills related to programming and IT. But it's not an easy task, if you ask me.
Nonetheless, I hope that new methods for making money with crypto would emerge over time as new cryptocurrencies rise on the market. With different consensus algorithms available, there are different ways to make money with crypto today. The easiest route (like staking coins) would take you a longer time than usual to be able to see a return on your investment. But at least, it's something that you could live up with as a sort of side income for emergency situations. Just my opinion
