I don't think tokens or coins received for simple tasks will be worth much, especially if tasks are like completing your KYC, making your first deposit, trading $1,000 worth of a specific token, etc. These are all very simple tasks and anyone can complete them, so even if a platform rewards users for doing such tasks, they wouldn't give them anything valuable because that way, they will have to lose a lot of money only on these giveaways and events and they don't do that.
For me, personally, the easiest money that I've earned from this industry was from $DOGS airdrop on Telegram. It literally only needed you to login once every day and collect your daily login reward, that's it, and at the end of the airdrop, it gave me around $100 which I wouldn't consider low for the efforts I had to make.
