SCRYPT profitability up today

Scrypt algo is up today for some reason. Is it because difficulty dropped or because more users transacted doge and ltc? I noticed the L7 profitability went up to 55 dollars a day last weekend. What may have happened there and will it return to that level of profitability?

Only powerpool and NiceHash did and the powerpool owner said they found a bug and wouldn’t say what it was. We’re they able to mine another coin on top of ltc and doge? We will probably never know
