A lot of people are telling you what they "would" do if they had 1600 BTC - invest 1/5, buy mining hardware with 1/3, keep 1/29 in a paper wallet, put 1/2 in a long term annuity, etc. When they'd actually cash half out via something like coinbase or BitStamp (which is based in the UK) and keep half or so as it is, to appreciate.
Go with your gut feeling. Don't fall for the hypotheticals; get some money for yourself, your family, etc and leave some for the future. That's my advice, from a fellow Pole
Oh, and a final tip - don't let people besides your parents know how much money you have. They'll start hovering around you not out of any sense of real camaraderie, but to get at your money. That's ruined a lot of instantly rich people I know personally.
