I will not contradict others when they recommend a hardware wallet, it is one of the safest ways to keep our private keys in the most secure environment. All you have to do is save the backup in at least 2 or three copies in safe places (preferably different locations), and always check that any information on the screen of the device is identical to what we see in the user interface.
I'm not looking to buy/sell crypto and profit USD, I'm looking for a wallet that holds my crypto that I can use to trade/exchange. Any info would be appreciated.
If you have no problem making KYC, Ledger gives you the option to trade directly through Ledger Live via Coinify exchange - but keep in mind that in that case the fees are probably a bit higher than in the case of Coinbase. Also pay attention to the list of countries where this exchange is
available.
