Good as what it was intended for.
I think many freelancers already aware of the blockchain technology. I have met someone who's a freelancer and has a client that looks to invest to different blockchain start ups. This doesn't means that many are into it but I think that there's a high portion of freelancers that won't have problem with it.
Freelancers have been using blockchain for a long time already. Decentralization reduces commissions. Records of orders remain on the blockchain. The cost of the order is automatically deducted from the customers account, so the freelancer has a guarantee that he will get money for his work. You can write reviews only after the transaction is completed, which protects against bots.
The specifics of work and payment allows freelancers to take the project from anywhere in the world.
