I've tried it a few months ago, I didn't like the rewards because of it really too little, some tasks for cents, at least for me it's not a good choice, but some people can get a nice amount of tokens and other cryptos on the platform.
and Cointrade CX, I've tried but this exchange Doesn't work for me, the page even loads, Tried to contact the support but didn't get any answer/help.
So this will be the challenge on their end, to get people who will use their platform.
If the rewards are too little, though maybe because the tasks are too easy, but if it will take long time to earn a decent money, users will find it not a good way to spend their time.
The team needs to find a way how to make those users stay actively on their platform.
Also, they need to list in a better exchange, at least with decent trading volume.
