+      Bitcoin is a free open source peer-to-peer electronic cash system that is
+      completely decentralized, without the need for a central server or trusted
+      parties. Users hold the crypto keys to their own money and transact directly
+      with each other, with the help of a P2P network to check for double-spending.

+      btc1 is an implementation of a Bitcoin full node with segwit2x hard fork
+      support.
