Well it sounds like you all are focusing and putting a lot of effort into trying to make BTC directly per day, when you should be using skills or labor to earn more $ and buy BTC. It may even be less effort, you could start a website selling some good or service and accept your local currency and Crypto. You could mow lawns in your free take and take that fiat and buy BTC. 1Hour of mowing a lawn could net you .0312 BTC, that could be .156 btc on a day off! All I am saying is don't spend tons of time looking for ways online to make a pennies or a dollar when you could just work in the real world and convert it if you want.
I dont think lots of people are earning much bitcoins each day because the miners are also not earning allot anymore i am now at the moment earning around the 5-7 bitcoins each day and that makes nice money
