As many developers visit HN I will use this opportunity to advertise the Stellar Build challenge[1]. I participated in the past and it's great. Especially to build some fun side projects, learn about distributed ledgers and earn a bit of money.
I agree to this. If you are interested in getting involved with building a crypto project, but can't justify the time: check this out.
Stellar runs a monthly give away of Stellar coins for submissions by developers. They set out a overall vision of projects, and reward a certain designated amount of coins to the finalists.
