Also, it is not going to be easy if you're going to have a lot of transactions, you could just use web wallets or something like coinbase when you just want to have fun and wanted to buy some cryptocurrency, I guess these paper wallets is just for people that are very careful on their investment the one that is going to buy put it in the paper wallet and forget about it.
Aren't web wallets the worst possible option (on top of not owning key) if you are having a lot of transactions as you usually can't manually adjust the fee, meaning you will overpay?
Most are saying that if you hold big amount BTC you choose paper wallet. what is the reason behind that?
Honestly I didn't hear people saying that and I got impression that people rather use hardware wallets in that case. Paper wallet is fine if you wanna store your bitcoin safely and for some reason can't or don't wanna invest in hardware wallet.
About biggest disadvantage, beside obvious one (easy to destroy/loose, not practical when you want to send bitcoin) I would also say that paper wallet is only safe if its done in a proper way and taken all precautions, and that's something that many fail at.
