As you can read on wikipedia
Proof-of-stake (PoS) is a type of algorithm by which a cryptocurrency blockchain network aims to achieve distributed consensus. Unlike proof-of-work (PoW) based cryptocurrencies (such as bitcoin), where the algorithm rewards participants who solve complicated cryptographical puzzles in order to validate transactions and create new blocks (i.e. mining), in PoS-based cryptocurrencies the creator of the next block is chosen in a deterministic (pseudo-random) way, and the chance that an account is chosen depends on its wealth (i.e. the stake). In PoS cryptocurrencies the blocks are usually said to be forged (in the blacksmith sense of this word), or minted, rather than mined.
First thing you need to do is download, open and sync your wallet.
You can download wallet from here.
There are some rules about stacking. First your coin need to get "mature". On Bitrad.io forum you can read it takes 8h, but I noticed it takes about 10h. Maybe it's 8h after it will get 10 confirmation not 8h from when you can see transaction.
Anyway if you have your wallet opened and coins that are on same address for more then 8h you are stacking. And if you are lucky you can mint new coins. Every block you extract will give you 0.5 BRO.
You can check if everything is fine and you are stacking properly in 2 ways. First one is easy but not so precise.
You can get BRO coins just by simple listening to radio. Just register here.
And of course you can buy and sell them on exchanges.
All links cointains reflinks. It cost you nothing to use them but it help me a little bit.
