There are several crypto freelancer websites but I never saw any of them getting more popular and going mainstream.
I don't understand why your website is limiting services only to USDT and removing support for Bitcoin and all other coins.
One day USDT could be banned, rebranded and stop existing, making your website essentially worthless.
Thanks about this Note , we can add more and more coins
But we see that many people have concerns about the fluctuations in the price of other currencies, so the decision was to have a fixed value without price fluctuations.
