It has been used in the past to inform users about important network events such as accidental blockchain forks. However, the Alert system also represents a large source of centralization in Bitcoin. Bitcoin versions introduced an alert system which allowed messages about critical network problems to be broadcast to all clients. The alert system has been completely retired.

Now a days the interest in cryptocurrencies like Bitcoin, ethereum and etc are blooming. In such era the interested people or individual would like to invest some some money in Bitcoin market but checking everyday the real-time value of Bitcoin price value in market would be cumbersome. So to avoid such problem I have made a small project which keeps eye on the current Bitcoin value and alarms you whenever the market value of bitcoin goes down about your given threshold currency or price from which you would be able to find whether it is right time to invest in Bitcoin market or not.
So this project is based on their kit So to have yours you can buy this from here. Twilio is online web service which helps you to send SMS, Voicecall, and many more functionality depending on some conditions you provide. So instead of regularly checking, the python program in this project comes in handy. For this the program uses the API of value of bitcoin which we have inserted in our program.
Basically this API we can found out from here. If it finds that the current market value of bitcoin is less than the selling price, the program automaticaly as a sign of alarm rings buzzer and also the LED as warning. To test safe mode, run Bitcoin with the -testsafemode switch. To override a real safe mode event, run Bitcoin with the -disablesafemode switch.
