Crypto Wallets are ideal for holding your crypto in your own personal wallet instead of on a centralized exchange.  It is safer and you have much more privacy and control over your crypto funds inside a private wallet, but there are some disadvantages.  The transaction fees are typically higher compared to centralized exchanges for swapping one crypto for another or sending crypto. Most crypto wallets have an on-ramp to buy crypto with cash, but there is no off-ramp, so you can not withdraw cash directly from your crypto wallet to your bank account.  You will need a centralized crypto exchange to cash out your crypto to your bank account.
