read.cash is a platform where you could earn money (total earned by users so far: $ 841,816.77).
You could get tips for writing articles and comments, which are paid in Bitcoin Cash (BCH) cryptocurrency,
which can be spent on the Internet or converted to your local money.
From the word itself you can notice the "Tip" word. It's pretty straight forward if you ask me. You only need to post something interesting. A simple link from any website or a picture that you find interesting. Make a short statement about it. Add some tag for the topic. That's it your done.
Then here comes the interesting part. How much Tip will you get for your post. That technically depends on how interesting your post is. One post can get you as little as 1 doge coin more or less. But a decent and interesting one might get you as much as 200 doge coin.
Wait but there's more. They have a daily and weekly contest that can let you earn as much as 200 to 500 doge coin.
You can find some post that have obtain some huge tips.
Also earlier this year 2021 they introduce and added Dogecash(DOGEC)
If you look at it again it's just look like BCH just with a dog face instead of a BTC logo on it.
I don't have much information at the moment but it seems the project goal was to revive the Doge coin.
