@masterfu: incidentally, I covered dogecoin in another post because it's one of the highest Bitcoin-producing scrypt coins at over 8 btc a day. Funny thing is, people made the same comments then like, "dogecoin is just one coin." I've analyzed over 100 scrypt coins. When I make a post, I choose a few coins that are repreentative of the larger point.
You're not supposed to make up your mind based on a single post. The idea is for people to do their own analysis. Start looking at scrypt coins and you'll see the same thing over and over again. They aren't priced that high and thus don't produce that much Bitcoin value.
The larger point that you might be missing is that regardless of its profitability, large-scale scrypt mining operations are forced to mine litecoin. The entire litecoin network produces a little over 218 btc worth of coins a day. If you are mining scrypt with large amounts of hashpower and paying 50 or 100 btc out per day, there is almost nowhere else to generate that amount of Bitcoin without mining litecoin.
I looked at fastcoin, dogecoin, dogecoin dark, litecoin, 42 coin, einsteinium, spots, lycancoin, globalcoin, sexcoin, franko, tagcoin, megacoin, and others just this morning in preparation for the last post.
Between Feb and Apr, scrypt.cc rewards provided an investor with a two month ROI and was paying out over 30 btc a day just to the top 20 account holders! khs price in early Feb was between 1200-1400. The returns given cannot be justified using any of the historical data we have on all scrypt coins. Don't take my word for it. All the data I'm using is available to anyone with an Internet connection.
