believe me, there are more absurd actions of many investors, of which 90%. I have heard that many people keep money in projects to earn money, because they are misled, as if it is a purse. I also heard that people keep on the exchange, where they buy bitcoin, etc.I no longer wonder. Just don't think about it. People have to go through their experience to understand how to do the right thing. Otherwise people will not understand

In my opinion, this is not the safest way. It is much safer to split into a lot of small purses and put on each very complex system of protection, or trade them in the market, which is the most advantageous option than a paper purse.

They are safe, but you need to understand how to create them first and to do not make any mistakes while you are using themtransfering all of your entire balance to there.
For me, it is risky and i prefer to use hardware wallets, at least, for my own safety

There are many types of wallets in bitcoin and paper wallets are one of them. But the wallet helps make things simpler

I think they feel its safer that way or the security is better even the exchange is not even safe you can split them to keep them safe .The wallet to use is the offline paper wallet and it features.I always opt for the offline paper wallet its my best

Maybe because they dont want to print the paper wallet ? You can lose your paper wallet if you not careful.
Some peoples decide to leave their coins on exchanges because usually exchange using cold wallet to secure the exchange coins.

Maybe the person is not capable or paranoid in keeping a physical copy of his account information. It varies from person to person.

Paper wallets are definitely safe but it is hard enough to secure it and keep it at a safe place. Paper wallets also has another disadvantage that it needs another wallet to spend the coins.
It means that the paper wallet can only store bitcoins in to it and if you want to spend it or send it to an address then you will first have to import it to a wallet (eg: blockchain.info) and then send the coins to an address.
This is the reason why most people tend to avoid using paper wallets.

The last reply from this thread is august 2018 , lol nice digging tho 

Anyway  , you are correct   . noobs dont engage on trading and investing , therfor they arent require to use some kind of a paper wallet or hardware wallet .

While pro and veteran crypto users are actively buying and trading , thats why they usually store their coins inside an exchange for lesser hassel and for lesser fees as well .
