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 not.
how many people do you think held their coins when price was dropping from $220 to $180 and how many do you think bought that day, and how many of those do you think dumped when price was $450 and it dropped hard. or all the other panic FUD daram that led to panic sells.
how many do you think will dump in the coming month of August, and how many do you think will hold and buy more.

it doesn't matter that you heard a coupld of stories about someone getting rich. there is always only a handful of people who don't listen to anything and keep holding for the real long term profit.

and this is just the start. we have started the mainstream mass adoption for less than 6 months and price rise is just getting warmed up.

I think its not too late to buy it. Others will say it too late now because of the value of it and its hard to obtain it because of expensive. Come to think of it, buying bitcoins can take you a lot of possibilities. Its not too late to buy because it is still increasing and also decreasing many people will come to it. Reaching its milestone is just a start, its never been too late.
