Basically to break this down in laments terms. You spend $300, you get nearly 1,000,000 coins. And coins suddenly go up to 2x their value, so you can make almost $600 back over night, or the next morning.
man, don't you know there is something called DVC/BTC pricing pair? and please look into the market depth of it first.
I think you misunderstood him. he's basically saying there's an arbitrage opportunity if you own bitcoins so why not make some money while removing cheaper devcoins off the market. It's actually a great idea but I don't have bitcoins.
I noticed it too but by the time I buy bitcoins depending on the price I get and if the ask moves up when I go to sell in USD then I may end up losing money. I did this with IXcoin because I was trying to buy some but there were no bids while over on the BTC/IXC variation there was huge volume. But by the time I got done buying and selling I paid an extra 25% for the ixcoins compared to the selling price in USD.
Still got a great deal but still, this only makes sense if you have a few bitcoins laying around. And I think that's what finshaggy was trying to say. The USD price is nearly double compared to the BTC/DEV price.
