Bitcoin was born from a small community and has grown fast. There are a lot of things you can do to support it and help others learn more.
Using Bitcoin is the first thing you can do to support Bitcoin. There are probably many cases where it can make your life easier. You can accept payments and make purchases with Bitcoin.
Be the network
If you have a good Internet connection, you can strengthen the Bitcoin network by keeping full node software running on your computer or server with port 8333 open. Full nodes are securing and relaying all transactions.
You can start mining bitcoins to help processing transactions. In order to protect the network, you should join smaller mining pools and prefer decentralized pools like P2Pool or pools with getblocktemplate (GBT) support.
You can help spread Bitcoin awareness by translating or improving translations inside important parts of the Bitcoin ecosystem. Just pick a project you would like to help with.
Bitcoin is free software. If you are a developer, you can use your superpowers to do good and improve Bitcoin. Or you can build amazing new services or software that use Bitcoin.
The easiest way to help is to donate some bitcoin to BitGive. Or you can help directly fund any project related to Bitcoin that you believe will be helpful in the future.
Many non-profit organizations are dedicated to protecting and promoting Bitcoin. You can help these groups by joining them and taking part in their projects, discussions and events.
Speak about Bitcoin to interested people. Write about it on your blog. Tell your favorite shops you would like to pay with Bitcoin. Help to keep merchant directories up to date. Or be creative and make yourself a nice Bitcoin T-shirt.
