Greetings! Please! I have a question, is there a console command or script that return the total coins circulating the block chain in that moment that the script runs?

I made a decision of going into cryptocurrency even with the limited knowledge I was having then, was in mid-2018 after a friend of mine told me the importance of Bitcoin to the economy. I was afraid initially at but after I have seen several use cases I decided to buy 7BTC and I left it in my wallet expecting the price to rise like the previous year in some months’ time due to my how I understand the market but it never happened. I watched series of YouTube videos for beginners but still made mistakes and losses, while trying to trade. In fact, it became worse that the value of my coins drop down to the fact of me almost giving up on the cryptocurrency market and selling off but I hold on to my patience and did a little research on how I can earn profit with my coins. After an intensive research I found a beginners trading post talking about a strategy on how to trade and make profit so I decided to give it a try and I contacted the person in charge, Mr. Dominic Connor. He took time to explain to me the different ways to make profit in this bearish market. I decided to give it a try and I invested 3 BTC of my coin, and it quickly rose to 9 BTC towards the end of December 2018, with the help of his signals in trading ther Alt coins and I was convinced that this is the best way to make a good profit from Trading. If you're still confused and don't know the step to take to profit in this new year I urge you to contact dominicconnorr33@gmailcom for all your cryptocurrency questions, strategy and beginners coaching and you will be glad you did
