Hi Kwattro,
No problem happy to try help, even if i do slightly over complicate the matter, I will try to explain it a little simpler ;/
Method #1
Moreover, I still don't know how to use the backup file (.dat) of the wallet.
To back up your wallet.dat file is simple copy and paste it to another safe location like a thumb-drive. the wallet.dat file is located in the following location (if using windows)
C:\Users\\AppData\Roaming\aerome\wallet.dat
Swap "" with your windows sign in usernameMethod #2
To back up wallet.dat is to do it via the actual wallet-qt client. So open your AeroME Wallet and in the top where it says "File" click that then the first option down that menu is "Backup wallet".
Click that and it will offer to save your wallet.dat file (usually to My Documents by default).
it is not very easy for me to understand all these things. What is clear is that staking is safe and the wallet must be unlocked.
Correct, staking helps both you (6% PoS) and the network by offloading some broadcast checking etc. Its perfectly safe, just be sure to "unlock" your wallet to stake. unlock means basically allow the network to use your wallet and become like a peer of the AeroME Blockchain network (in staking terms).
How can I open it on another computer? Can I switch my wallet by just copying the backup .dat file and opening it in another .qt application?
Your wallet.dat is your file, thats what basically contains your coins. You can open on another machine if you need to. but if you encrypted it with a password then be sure that you keep that password safe. To re-open on another machine you will need that password to decrypt that wallet.dat for it to run on another machine.
The AeroME (wallet.dat) will only work with AeroME wallets for example you
can't use your aerome wallet.dat inside the Bitcoin-qt wallet.. They are not compatible.
Aerome wallet.dat works with the AeroME blockchain/wallet...
I can't find a way to browse for the .dat file. I ask this, because I would like to stake my coins on two different machines by copying the .dat file from on to the other every time. Is this possible?
You will need to split your coins onto two separate wallets. So on machine #1 have your coins there.
Then open second machine, download the Aerome wallet again there.
Then, Sync that wallet on the second machine.
Generate a new address on the second machine wallet
Now, from the first machine sends your coins from machine #1 (Wallet A) over to machine #2 (Wallet B) then you can stake those bad-boys on two machines.
There is not "Rewards" advantage to staking on two machines btw. You will not gain extra PoS rewards. I just thought i would state that. But from a security/redundancy perspective you have split the risk and not have all eggs in same basket which is smart move i guess. I maybe just missing the point though
copying the .dat file from on to the other every time. Is this possible?
you can have multiple wallets for AeroME as with any other coin. there is no limit to the number of actual wallets you run, You may have port/connectivity issues as a side-effect of running many of the same wallets on the same machine but apart from port-forwarding and some .conf file wizardry you can run any number of AM wallets.
But in answer to that question NO you will not have to keep making backups of wallet.dat and move to second machine. As the Machine 2 (Wallet B) will be independent.
Think of each wallet as independent just you have half coins in one wallet and the other half in the other wallet.
Let me know if i missed anything out,
Majika.
P.S. I will have a hunt around later to find a nicely compiled guide that maybe will explain security issues a little better than what I can.
And outline some common "Do's and "Dont's" about cryptos security in general. With some basic concepts which may help you a bit better understand.
