how I would be able to cash my bitcoins out in the future?
Of course, the best method is likely to spend your coins on items you would purchase anyway.

http://en.bitcoin.it/wiki/Bitcoins_In_BerlinThink about how would you liquidate $54k in gold, and you'll get the analogy.
Not just an analogy, but another idea.
You can buy gold and silver bullion with bitcoins, and then trade the bullion locally for cash.
There's also another method. Kapiton.se is a market exchange. I don't know if you need to verify your identity to register and use that exchange. Let's say you don't. You can then trade BTCs to SEKs, but then not withdraw anything to your bank. That will give you the ability to convert BTCs to SEKs so that you aren't further exposed to the BTC/SEK exchange rate risk.
Then at some future point in time, you can offer to sell bitcoins for cash, and when you find a buyer you simply use those SEKs in your account at the exchange to purchase bitcoins at whatever is the current exchange rate at the time and withdraw the coins for delivery to your buyer.
