...what exactly do I tell my wife is the reason I failed to win the FreeBitco lottery last week.?

I am surprised to know that you tell your wife about these lotteries.

Surely it is a lottery and anybody can win or lose, although having more tickets increases the probability but does not guarantee one. Even a single ticket owner might be a winner if their ticket is a winning one.
It's good it was credited but two hours later I saw it in the history well after launching my tricks. It was the first time I saw that. I have done no offense. I've been playing for a long time
Deposits get credited after one network confirmation which can take long depending on how much fees you paid. Although recently the fees had sky-rocketed, they are down now to manageable levels and they should not take long. If you have any other questions, dont hesitate to ask here.
