A cryptocurrency wallet is simply a digital wallet where you can store and manage your crypto and digital assets like NFTs. For optimal security, every wallet comes with a public and private key. Once you set up your wallet after your due research, you can simply connect it to an NFT marketplace for digital collectibles and start buying. The assets will be safely stored in your wallet. However, make sure that your private key is known only to you. For the best security, you can opt for a hardware wallet. The top crypto wallets include MetaMask, CoinBase Wallet, and Trust Wallet.
