Unfortunately, there is always risk involved in staking coins. At first glance, staking looks like a great passive income idea, but it's too much of a risk in my opinion. The questions you ask say you have very little experience in the world of cryptocurrencies. Before you invest, I suggest you read a lot about staking first. Also take into account that by investing in staking you freeze your funds, which in the situation of a bear market will probably be a big loss for you.
