Everyone should use a hardware wallet, ledger, trezor, etc. for coins and tokens. I can't understand how someone could store them on an exchange or phone wallet and expect to be safe. Anyone can be scammed if the conditions are right, that's why your attitude must always be NO.
Hardware wallets are only superior in terms of asset storage and are also safer, while for other things I think they still have shortcomings, because for those who store assets in any exchange it is also only temporary for the sake of convenience in trading, while storing assets his investment in the long term, it's obvious the choice is a hardware wallet and nothing else.
Still this means one thing , that storing your funds in exchange is the stupidest thing a investors holders will even had , there are so many cases that funds lost in exchange and also hacking is very a vulnerable thing happening in exchanges .
store funds inside exchange for some time while in trading and take out everytime you are done .
this will keep you from not being a victim of this mistake action.
