The title says it all: What would you do if you had mined 500 BTC back in 2011 and remembered that you still have them?

Would you hold? Would you re-invest in mining? Would you convert to fiat spend it? If so, how would you 500 BTC to cash?

I've been wondering about this. I have a few early adopter friends (not that rich though), yet I was never interested in Bitcoin myself that early.
