cryptocurrency market started to grow day after day, and everyone now started to own coins, so the question now which come to all the coin's holders , how to protect your digital coin from losing, stealing, hacking, etc ?
If possible, do not save them in an exchange wallet, unless you are a day trader. Save them in hardware wallets such as trezor or ledger nano. They are safer as compared to online wallets or desktop wallets and mobile wallets. Private keys should not be shared to anyone, strictly. And they should be kept somewhere very safe, preferably somewhere secret.
