The Advantages are.
Fastest way to complete transactions
Ideal for holding small amounts of cryptocurrency
Some are able to manage multiple cryptocurrencies, transfer amounts between them, or be directly integrated into an exchange
TOR network can be used for more privacy

Disadvantages Are
Users are susceptible to phishing scams, malware, insider hacking, DDOS attacks, and outdated security measures
Your wallet is “out of your hands” and coin information is stored on a third-party
Your computer is open to malware, keyloggers, and viruses

I prefer web wallets but with the nesecery anti virus - trojan - phising software
