Why I use Sweatcoin? - Earn coins for exercising

Many of you are probably users of the dapp on Hive blockchain called Actifit, which gives out rewards based on the amount of excersice you do in a day and on your written report which you have to give at the end of each day. These reports can you then see on the blockchain and on some different front-ends and they can also get additional rewards from people votes on your content because they think it valueable.

Sweatcoin is another app that has a similar idea. You run the app and during the day the app records every step you take. These steps will then be converted in to their native coin called Sweatcoin.
You get this reward with doing anything else than just excersice and turn on the app. There are some ways you can earn additional rewards, you can watch 3 short commercials each day and get a random reward between 1-100 Sweatcoin each time or if you have a big network can you invite people to join Sweatcoin. For each sign-up you will get 5$ in Sweatcoin.

One difference between these apps are that Sweatcoin is actually not on a blockchain, so their tokens only exists inside their app and there is no exchange where you can trade your coins.
So why would you then use this app if you can't withdraw the money? Well, there are actually a big community where you can trade your coins on discord/reddit.
I have so far earned 10$, not so much but I'm planning to increase my use of the app so in 2021 I will definitely earn more.
All my earnings from here will I put direct in crypto. I belive these are the tools to get the greatest returns for the coming future.
