THis parlay is already lost, Borusia, Fenerbache, Ajax, all lost, lesson learned to stay away from Europa league and Champions league. Stick only to weekend matches, they have better chances to win as you have much more info regarding specific championships ,team form and teams are from same country. Anyway it was an accumulator with odd 11 or more so worth a try a few mBTC. I lost 4.3 mBTC. No problem, I have a lot more to try in weekend.
Its not the lesson you should learn. In weekand matches there are also surprises!
The lesson you should learn is not going only with the favourite team, especially in europe.
