Even the blind can see that crypto Currency is making people millionaires all over the world just because they present the holders of such currency with the financial freedom and opportunity to accrue large amounts of wealth base on currency investment . But my question is that, is it late to buy bitcoin? Should i wait maybe bitcoin price will decline after 1st August meeting? Please i will welcome your advice so that I can make my decision on crypto currency investment.
No. it is never too late to get involved with bitcoin. Bitcoin value will continue to grow as time goes on because new people will be buying bitcoins everyday. The more people are trying to buy bitcoins the more valuable bitcoin is going to be. High bitcoin demand is what is driving the bitcoin price. As you already know new people are buying bitcoins everyday and the demand of bitcoin is higher than the supply. So, the price will continue to get higher everyday, even when there is a correction the value will recover in no time. 
A friend of mine once told me that "unfortunately now it's too late to buy Bitcoin. I wish I bought it when it was below $600, not long ago". That was when Bitcoin's price was $1,700. And now we can see that it wasn't too late at all. )
Yes, you are absolutely right, the demand of Bitcoin is higher than supply and that's why the price is going to rise more in the future.
