Thanks guys... but I do have a computer available half the day... I want to leverage it into some sort of staking while I'm asleep etc. I still don't have a clear sense of what you think is the best coin/token for doing that.
There is no need to spend your computing power or pay more electricity bill, if you will keep your computer running whole night either you will end up with broken computer or paying high electricity bill valued more than what you could earn from staking those coins.
You might also look into coins that are using DPoS (Delegated Proof of Stake) where you don't need to have a wallet running by yourself, like for example Lisk or Ark.
Both are available on Bittrex.
Go with this suggestion.
Does staking require more electricitiy? If yes, is it as bad as mining using GPU?
Example will be Qtum - I'm put off buying Qtum as I do not want to consume more electritiy + I think the risk of being hacked is higher if I have to open the wallet all the time.
Thanks.
No, compared to mining it doesn't need any notable GPU or CPU power.
