When you cold stake, the coins are staking like a pool. But you still have 100% control of them, and get the rewards, and you can use them whenever you want. It will still be shown as full funds in your wallet, but when you make transfers "send coins" you will have the option to use the ones that are staking or still in your wallet or both at the same time.
I didn’t have any idea how cold staking works though it was more or less defined in the wallet. Who will receive the rewards? Is it me or the running node? Also, what information I will be sharing with the node? Can you please share more details on the privacy issue? It would be good.
Can I do it through VPS? Like installing a wallet on VPS and keep it running all the time and defined cold staking in my wallet? Or something else I need to do?
You will receive the rewards for the % of coins you are staking with within the "Pool", so staking with others is ofc better, as it's like mining more coins = more rewards. " if you don't have Billions of EMC"
Your keys are always kept on your side, and never shared with the "pool" Coins Deligated will be noted as delegated in the chain and the pool owner will only have the option to stake or not stake the coins, you will see on your wallet if they are staking when sent to the "pool". "it talked 600 confirmations before staking begins"
Pools keys ext is also only stored on the pools end, so even if the pool's wallet get compromised your coins are safe! " Note that you always need to keep your key safe. don't share passwords ext"
If you want to use the stake coins you can use them in a transaction when ever you want, just select them when making a transfer, so there is no locked tim! " NOTE THIS EXAMPLE THO! If you have 1.000 EMC Deligated to cold staking, and you want to use 500of them in a transaction, 500 will be used in the transaction and the remaining 500 will be sent back to your wallet and end the staking, and you manaly need to re-send the 500 to the staking pool again for it to stake! so ONLY use them in a transaction when u REALY need it, as it will end the staking!
There is no pool fees or profits from just running the "pool" from the wallet. Running your own Ubuntu server on a Raspberry Pi and building the node "wallet" on there I cant say if you will have the option to enforce a fee, but I don't think so at this moment, many there will be a vote/update for it later?
But it's ofc good to run your own node, as it makes the community grow as people see a lot of activity and also for you to make a bigger profit if you can get major EMC holders to stake with you.
Hope this answerd some questions.
