Heh... My wife is also telling me some things but I usually kindly and gently explained to her that she is not familiar with all the things that I am, so she's not the best advisor that I can have 
I also think, if the wife does not deal with crypto-currencies, then she can not give the right advice. You have more information than she has, because you are constantly here and know what is going on to the market. To sell coins is not the best solution now.
