Not sure what it is.
Two transactions with that amount on the 13. Sept.:

13itfquZ5Gpi9VruvPxk7wnVL4wPMNfuL7 sent and 0.40808398 BTC went as change back to itself.
~30 seconds later [2] 13itfquZ5Gpi9VruvPxk7wnVL4wPMNfuL7 (0.40838398 BTC - Output) sends to 1PcxahpxQ8qA5US912VcLvxnHy3D9Lt45Z 0.02170012 BTC and the change of 0.38658386 BTC again went to 13itfquZ5Gpi9VruvPxk7wnVL4wPMNfuL7
So, whoever posted the above (in a few locations) actually never received 0.40808398 BTC. A fake comment to attract new users / fresh capital?
