I just pulled all of my bitcoins onto my mac from mtgox. I am using multibit for my wallets. This computer will eventually have very limited access to the internet and will be considered my "vault". I exported the keys onto an external hardrive, as well as several flash drives that I will keep in different locations. Also, I will print out my encryption password and keep several printouts in several locations as well.
My question: should I delete all of my wallets from Multibit and rely only on the keys that I exported? Those keys are essentially, my bitcoins, correct? This money is savings and I will not need ready access to it except to sell it when they eventually hit $10,000 per bitcoin
Please help. The more I read the more confused I get!!!
