Thanks, that was a helpful explanation.  I've been reading about the exchanges and other coins (mostly ETH and LTC) and I saw the big ETH crash last week.  Amazing to see the "wealth" vanish in a second.  

I thought you might have been talking about trading on an exchange, but I thought maybe you had a successful method you'd be willing to share some hints!    

I'll keep researching and may try to dabble in the markets a bit.  The idea of creating coins thru mining seems safer for my money than trying to buy low and sell high... I don't feel that lucky!

Thanks again
