I want to move exchange coins to some secured wallet, but I am unsure which is best wallet, offline desktop wallet, paper wallet, or hardware devices like Trezor. Kindly give me suggestions.
the best wallets will always be hardware wallets, let it be trezor or ledger wallet, the reason for this is that with them even you dont know the private keys, they are stored securely in your hardware wallet, however, for all others there is always a chance of hack or theft as the private keys are visible.
If one is not able to buy hardware wallet, next best option is paper wallet.
