Bitcorn is what you grow in this Bitcoin-based game. You hodl CROPS tokens, and then 4 times a year you can harvest Bitcorn. That's it, that's the game, and yet it is great fun.
By hodling at least 0.001 CROPS you can customize your farm. This includes naming, description and even choosing a geographical location so long as nobody else already has that place for their farm. Custom images can be uploaded too, and there are some really cool ones!
CROPS tokens are Counterparty assets - this is a meta protocol on top of the Bitcoin blockchain. The easiest way to start is to go to counterwallet.io and open a wallet. Then add BTC, exchange for XCP (the counterparty token) and then you can get your CROPS.
The first harvest is beginning of April, so now is the time to get started farming! For much more info, see my detailed post here: https://is.gd/g8bFxN
