Are you too lazy to have to type a website to get the current rates or to check every hour or minute for the new bitcoin rate?
You can set which coin as well as how frequent you want it (every 15 minutes, 30 minutes, 1 hour etc ) to send you post notifications about the current rate.
If there happens to be any surges, say Litecoin drops $20 in value or increase $20 in value, it will also send post notifications to alert you on that and you can decide whether to buy and sell based on that.

I wouldn't recommend it at all. As a trader, I usually use PC anytime and anywhere. I use Cryptopia for trading, but Cryptopia doesn't have a mobile app. Since Telegram is a mobile app, that will took much longer than just looking the cryptocurrency rate at Cryptopia. This channel will be good for a worker who don't have time for looking the cryptocurrency rate.
