other than bitcoin but you want to still earn money online which mean you ask alternative to earning money but skill and knowledge is required to do so because most of companies will Prioritize the person with high skill such as programmer or something else and if you have it i think it would not difficult to get the job
If you have multiple skills then you will find multiple ways to earn money but not all have very high skills and if you don't have those skills then you can always develop the skills and can earn money so if you are capable to learn new things then there will be no limit for your earnings as I don't have any technical skills so I learned trading and now I am earning good amount from it.

Yeah you're right skills is always their we just need to develop it, but on my case i know I'm capable to earn good amount of money online and everytime i'm trying to learn new things to explore more becoz i know the more knowledge you gain the more money you earn
