2009 Bitcoin and only Bitcoin did we know about 
But like 2011 2013 2015 and 2016 more and more cryptic currency are all around up will they rise will they succeed I wonder 

The new one about is silverbits don't no too much but three staring price is high so we will have to see 

But Bitcoin is here and is working well so can't see that many new currency bring as big as Bitcoin do u 

What do u have to say on it please comment below if u want
