To be honest woth you, I am not a crypto expert. I am new to crypto and have only a small amount of crypto that I purchased one time when the price was down. I should not excite myself on this because the volatility of crypto is not all the time favoring us. And then stumbled on storage where to store right the coins called Cold Wallet. It said that a commercial non-custodial cold wallet is one of the safest methods for storing your keys. But the price is $200 just to store our key. Dunno if it is safe. It said that cold wallet is safe, hence it is not connected to the internet or another device so it can't be hacked.What can you say?
