Pros:

• This is a good innovation especially for crypto traders who want to check prices all the time
• The prices' updates are being flashed real-time
• Automatic night mode. This will give convenience to users to save time adjusting the settings
• This will save a lot of time instead of checking the prices online every single time

Cons:

• The apple watch screen is very limited. It can only show up to 4 crypto coins prices at a time. This can be inconvenient for someone who trades countless cryptos
