The ability to get rich overnight certainly exists, if a good ico explored it could work, but I think that it is less than 2 years ago
Crypto is one of the avenues of getting rich yet it should be understood that it does not happen overnight. Getting rich in crypto requires a lot of dedication, hard work and patience. People do not see the essence of crypto investment because they want to get rich quickly, hence, hurriedly invest in projects that follow the pump and dump trend.
Remember, one key to success is patience.
