Cryptocurrencies can be kept online or offline. If the cryptos are kept on the exchange platforms or other online platforms, it can be lost due to hacks.
So it is important to choose the best wallets that are safe and secure. Please help me in choosing the safest cryptocurrency wallets
I have suggestions depending on its use, as a market observer or more or less a trader, I will save cryptocurrency on the exchange platform. Because of the ease of management. from what I see because you look from a security point of view and avoid hacking it would be better to use hardware wallets such as ledger and trezor.
