is it anyone cant to get my btc in terzor?

and if i lost my terzor,how can i get back my btc?

If you can spend few hundred dollar for hardware wallet like trezor than yes it is safe cold storage method. But if you can't pay for hardware wallets, i think paper wallet can also work as cold storage and if you can keep it safe and out of internet it can provide same level of protection like hardware wallets.

Edit: Typos

WTF? This is completely wrong.

OP, don't let sig spammers influence your opinion, they mostly have no clue what they are talking about and the most possible reason why they are posting here, is to raise in rank for more money. In reality there are a lot of different cold storage methods (you can even carve your private key in a stone if you like). Some are more secure than others and some can even be pretty insecure, like a Brainwallet. You can choose the one that fits your needs.

ok let me read it,because i ready to put a huge amount on btc for keep my money anonymous

if you are looking for a decent level of security then choose one of the links above to cold storage such as hardware wallet or paper but if you are paranoid that some people may be, you can make the private keys manually (by hand or in other words with pen and paper) for that you need a 16 sided dice to roll and get a 100% offline no computer generated random number! and pen and paper to write it down and convert it to a private key

what does cold storage mean?

Yeah, thinking the same. You found a very good solution. Paper wallets are simply the cheapest and most secure option out there. The only thing you must be aware of is that after importing the private key again into Bitcoin Core and sending a transaction, the amount leftover will be stored at a new address - so don't delete your wallet.dat afterwards!

For printing paper wallets the best printer is possibly a needle printer, because there's no ink decay if you store it for a decade or so. Laser printers are also acceptable if you laminate the printout. You should avoid ink jet prints, because they tend not to be long-lasting (especially when exposed to UV or chemicals).

Oh sorry about that AGD, the cold storage that I have known is Trezor, other than paper wallets and physical bitcoin I have only had experience with hardware wallets and have only use online bitcoin storage, I may not have any knowledge about other stuff when it comes to bitcoin like you do, but thanks for showing the link about other cold storage I have learn a lot because of that and because here in our country other bitcoin storage are not popular or maybe no one really is using it here.
