There are many ways to participate in Badger. You can just stake Badger (buy it in an exchange, Uniswap or Sushiswap) and then just stake Badger.
Or you can provide liquidity to the WBTC/Badger LP - there are two of them, one is in Uniswap and the other in Sushiswap. But if you do that, you have the risk of impermanent loss (this can be compensated or not by the pool fees and the higher farming rewards).
You can also participate without Badger token, just using tokenized bitcoin (wBTC or renBTC), deposit them in Curve (in the vaults that are supported by the Badger app), and then deposit your crv pool tokens on Badger (this will earn you Badger, Digg plus enhanced yield).
People in the community are always happy to help, I am happy to help. But there are also bad actors in the crypto space and in any community. If you don’t learn how to get your way in DeFi (is not complicated), someone might try to scam you. There are several guides and videos online that will help you. Even if you prefer to rely in someone that you can trust, it is important to have the criteria to see if that person is acting in your best interests or doing it wrong.
