wow its big amount for me, if you hold it until this year, I can not imagine how much money you will have by selling your bitcoin. with 500 btc, if I sell only 10-50 btc, I can buy a house, going to some place, vacation for a week or more.

I only have between 1 until 10 bitcoin and I really hold for a long term because I am sure that the price will be higher than this year. I only use small part for trading and for other thing.
