Staking generally has a very low difficulty because proof of work is not the main way that new coins are minted. So if you own a staking coin you can use a regular laptop to stake and just leave the wallet running.
Actually.... I'm staking a coin Equihash PoS. I've heard on their community that staking will be more difficult in following days. What do they mean by that. For example if im staking today 50 Coin, in "following days" i will stake less example 30 Coin.. I'm right?
There is a certain degree of risk because you need to keep the coins on an online computer and there is some degree of risk.
I'm staking on desktop Wallet QT and can you tell me more about of this risk, What do you mean?
Can i lose coins?
