Regulation should be seen positively, do not fear regulation but embrace it.
With clear rules regulation will legitimize the space which in turn will make things better for both ICO makers and contributors.

Im try to understand verifing bitcoin transaction but I cant find this part anywhere. Summary, the proces before forming blocks. My questions is:
1) when i send transaction who validate it ? Here I think, who can check and found that I haven't got enough money in my wallet. Example; I send 100 BTC but I have only 50.
The problem is bigger becouse in my prior transactions, refund come back on "new" wallet and who can trace all my wallet to sum how much I have in that situation. I dont speak here on double spending. I undestand that part.
2) can one transaction go by mistake in two blocks, and who prevent this ?

If you are worrying about simply sending transactions that get delivered all you need is to make sure the transaction fee is high enough.
Use something like https://bitcoinfees.21.co/ to determine what the best fee is at the time you send your transaction.
Core is the best Desktop wallet however for many the syncing could be an issue because of storage requirements, internet bandwidth, etc.
Electrum is a slo a good choice otherwise Exodus and Jaxx are also easy to use and don't require any syncing.
Make sure you always protect your private keys and wallets following best practices.

I am new to bitcoin and I just bought 0.12 btc few days ago from localbitcoins and I use electrum mobile wallet to keep my Bitcoin.
What exactly is fork? Or Hard fork?
I heard that those who own bitcoins before 25th Oct will receive Bitcoin Gold. How does it actually work? Do I receive Bitcoin Gold automatically in my electrum wallet or do I need to do it manually?
And if I have 0.12 btc how much would I receive in bitcoin gold? And does the value of my btc change ?

Making your own paper wallets might be your most inexpensive method, but you have to know what you doing or it will be your worst nightmare. There are a lot of advice on this forum on creating your own secure paper wallets, so you have to do some research before you attempt this.
Buying a hardware wallet will be a bit more expensive, but it is a lot easier and it gives you easier access to your coins. The other methods < Desktop wallets and online wallets > are the least secure, but the easiest method to store bitcoins.

I got a mail from trezor yesterday, they seem to have dropped their shipping fees within the EU, so a hardware wallet does cost less than $100, wether it be a trezor or a ledger nano S.
That being said, my own view on the topic:
Safest:
- hardware wallet: both reasonably cheap and easy to use
- airgapped pc: expensive and a little bit harder to use (you always have to transfer unsigned/signed transactions between an online and offline machine)
- Paper wallet: very cheap and very secure if generated in the correct way, but hard to use (you have to sweep and discard the paper wallet each time you use it, then transfer the remaining value to a new paper wallet)
Medium:
- Desktop wallet: free, but you need a clean PC and you NEED to encrypt your wallet (using a strong passphrase). Virusscanners/firewall are a must have
Unsafe-ish:
- Android/Ios wallets: I call these ones unsafe because it's harder to verify the wallet's signatures, many people know less about their phone's OS than they know about their desktop's OS, and phones can easily get stolen/lost
Unsafe:
- Any wallet where you're not the (only) one in controll of your private keys. This includes exchanges and online wallets
Agree that's a good list, hardware wallet seems to be the most secure, however you can achieve very good degree of security with certain desktop wallet including Bitcoin Core.
