There are other good and easy sources of income when it comes to cryptocurrency, some which are participating in airdrops, buying tokens and staking them to increase the quantity, another interesting source of income is mining. Another sources of income is participating in bounty.
I like all the resources that you have mentioned for making money but it is not good to use all the web you are using crypto. I think making an investment for long term holding is the best way to get profit and also really good to use bounty as it's way to get free earning and mining is optional as only affordable people can use mining because of power bills so if you can afford its well and good.
