Don't need 'em. Nobody needs 'em. They suck. End of story.
Edit: I deposited around 25 cents USD in BTC when I first opened an account in 2011. Never did anything with it. Later I found out that my account was completely gone (no password retrieval, no record of my email, no record of my account name...nothing) and so were my 25 cents. To this day, I will adamantly claim that Gox stole 25 cents from me and never notified me about deleting my account. Password strength was 20+ random alphanumeric characters and other symbols. I want my quarter back, assholes.
25 cents, hahaha.. Mt Gox probably cancel off any account which has less then 1 dollar after inactive for sometime...
