Staking coins for the most part is pretty risky. All this DeFi stuff is not sustainable at it's current levels, so first off you want to make sure that you are okay with that..because things could come crashing down at any time. When it comes to bitcoin, my personal suggestion would just be to hold long term and let things ride out. As I always state, one must make sure they've got a well rounded portfolio with traditional assets first and foremost.
Even the vaults that are deemed as safe, contain a pretty high risk factor. Despite investing mostly in stable LP pairs, I've had a near miss a couple of months ago, with one of Iron.Finance's contracts. Even though both coins were relatively stablecoins, after an exploit on Polygon, Iron lost significant value, while Steel was zeroed. Fortunately, I was in Binance Smart Chain, and it wasn't directly affected.
Currently, I'm staking through Pancakeswap, USDO - BUSD, it's thought to be a relatively safe investment, without too much risk involved, however, as I've already mentioned, the risk is always there, rug pulls, exploits etc.
