How worth it is it to invest in cloud mining?

I have been recently been extensively browsing the internet looking for the best ways to make money using cryptocurrencies. I have found some preety interesting ways mostly consisting of mining and trading. However I'm really intrigued with mining due to it's seemingly low effort and sort of high reward. I was wondering what other people thought about cloud mining in websites such as genesis mining and hashflare and wether or not you thought it was worth it.
Thank you!
