Great thing about btc is that as it's gaining adoption, and there are more and more blockchain projects out there, there are more and more jobs you can get paid for in btc.

So it's both - the whole industry is exploding, and the btc itself getting more popular in widely used.
I remember in 2013 you could get paid in btc for dev work, little bit for community and communication work, but not much. Since then the whole space totally changed. Since 2015 I saw a ton of opportunities in all spheres that a project or a startup needs paid in btc.

What always worked the best for me, is connecting with people IRL, going to local meetups, and bigger conferences (I don't mean those bullshit corporate blockchain this and blockchain that conferences that started to pop up every day of the year since last year) but a decent ones. Local meetups - trading ones and focused on technology usually have the best people - those who been in the space for a while and know how to see bs from a legit thing, pointing you at good bigger events and also work deals.

Bounties and short term project launch tasks are the most obvious ones. But many projects launching tokens atm would be delighted to get in house social media and community folk. Capital in the space is by far more abundant than skills and knowledge, that's for sure. It is a bit of a hard work to actually see what token projects do make sense economically and functionally and which ones are just lame ones that are going to die. But when you spotted a good one, they would definitely need people to come and help on all sorts of positions.

Another thing I have noticed that a lot of projects that are launching tokens or decentralised infrastructure are not quite sure how to find good community managers. I usually go and check for people on btctalk who managed bounty campaigns that I thought were cool and well done, and head hunt them this way.

I also came across this reddit but I haven't used it yet to post offers.
