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.
For normal use, the best is definitely hardware wallet, like Trezor and Ledger. These hardware wallets have been made with security in mind. You can even use these hardware wallets in infected computers. Your funds will be safe as long as you keep your backups secure.
As for paper and offline desktop wallet, those two are best for cold wallet, i.e. you're not going to use the wallet for a very long time.
