We all know that cryptocurrency is an extremely unstable market. It may change even every minute or every hour. It is not unusual for cryptocurrency prices to rise and fall several times during 24 hours a day. There are lots of earning opportunities that happen for us during this heavy price movements. But there is a problem that I don't know how to cope with it. Sometimes you buy a coin at a certain price and wait for price rise to sell it but you can't check prices 24 hours a day! That's impossible! Once it happened for me that I had bought a coin and when I was asleep, its price had increased during the night for a few hours! When I woke up in the morning, I was so unhappy that my coin's price had fallen and I couldn't take advantage of the golden opportunity that happened last night! Luck will only knock on your door once, if you don't respond, it will go away!
What should we do to prevent missing this kind of opportunity? It would be nice if there was something like a price movement alarm which could inform you when the price would exceed a certain threshold.
