So, how much did your mistakes cost? Did they cause you a serious psychological blow? What were your mistakes, did you learn from these mistakes and do you apply this knowledge in practice now? Were these mistakes simply painful, dramatic or catastrophic?
I can only think of was first, is the technical error or internet error when i spin, and accidentally click the spin button instead change icon of the bet which take all my balance in one spin and yes it came in a lost bet so, that's unfortunate.
