Bitcoin is almost 14 years old, countries have already regulated it or passed laws considering it legal tender, each new day another ATM is settled somewhere in the world, the most influent men in the world confessed they own bitcoin or have interest for it, big companies have been going through the same path.
Unfortunatelly there isn't any bitcoin micro tasks site around with the same weight those mentioned sites have on the virtual environment...
In your opinion, why do these popular platforms act like this and completely ignore bitcoin? And why doesn't a platform of the same kind, but using bitcoin, is able to develop itself to compete against the big ones?
We have many freelancers sites that accept Cryptocurrency I remember hiring one on
https://www.banigig.com/, unfortunately, freelancers and userbase are small, big companies like Fiverr like to use Paypal because they want to protect their clients because of the chargeback and also to verify their users and freelancers, Fiverr three years ago accept Bitcoin I hired people to do writing job and always pay via Bitcoin
