Paper wallets are safe but they are messy: you can lose your paper wallet or you may make a lot of copies but then you might unintentionally reveal one of the copies to somebody.

However, what data do you have to back up your claim that it is not used? I am sure some people use paper wallets.

I don't use a paper wallet either. I divide coins into many pieces which are stored on different resources. This makes storage safer. Paper wallet is very inconvenient. The transaction price in December was very high. The transaction confirmation time was also very long. This makes it uncomfortable for traders to use a paper wallet.

I think it's more secure when your money is digital rather than fiat because we all know how digital money is very convenient and less mass if you have it, you will just be needing a trusted wallet for your money. Also fiat money is very complicated when you are buying something and your cash is big, so your change would be many fiat money including coins but if you pay using digital the you only payment directly from your digital wallet and fix digit is deducter to it no more change and many coins.

Most of the people in crypto did not use paper wallet, they putting their funds in exchanger because in traded you can easily use the funds.

I just wondering why some people don't use paper wallet to secure their bitcoin, Some of them are just putting to the exchanger and trust their funds that no assurance of safety.I don't understand why they did not use the most secure way. So I think the paper wallet evrybody should be used.

Actually, if the paper wallet is more suitable for those investors who invest long-term, and most who put their bitcoin on the exchange are those who trade fast.

People have their own different ways to secure their Bitcoin, some uses cold storage like hardware and paper wallets because they will hold it for long term investment, while some uses hot wallets because they do trading but of course this cannot be considered as secured as you are trusting them to have full control of your funds, the other reason why people store their Bitcoins on exchanges because they want to get rid of transaction fees and be able to trade easily whenever they want to buy altcoins at the dip. Paper wallets are one of the safest way to secure your Bitcoins but not all people have knowledge to create one, you also have to be careful on which software you will use to create one.

Everything comes with a responsibility.
Paper is a good idea. I have always been looking to save info on that.
BUT
Once the paper is lost it will be a hell for you.

Maybe Paper plus USB device.

So we have 2 places to secure data.

why some people dont use paper wallet? I think they dont you paper money because paper money is tiny and easy o loose and misplaced, better to use paper money if you have a huge amount of bitcoin and if you want to hold it for long time.

some of them are traders which means they have to store their funds on exchanges while they are trading. and trading is not something you do one day and give up doing the other, your funds need to be active constantly from one order to another and sometimes you need to have an open order on exchanges so you keep some funds there eventually.

anyone who does it for any other reason is taking an unnecessary risk and they need to transfer it out to a cold storage (only one form of cold storage is paper wallet).
