Hardware wallets are considered the safest of all wallets today, but I think many people are used to software wallets and during use they have almost no problems, so they will have no reason to buy hardware wallets.
I still use a hardware wallet because in my opinion it is the best way to protect my bitcoins but I have a friend and he is also an investor but he uses Electrum and runs it on a computer without internet connection. He says he feels safe using that storage method and he hasn't had any problems with it since he entered the market so far. I advised him to equip himself with a hardware wallet which would be more secure, he said he would buy but didn't say when.
