Definitely not fully spending on a Lambo is what we hope for but with over 5 million entries, treat it as another lottery 
What the heck! Thats a lot, good luck to your entries then. Thanks for the clarification above anyway.
actually 5 million is very very low compared to their lottery and also considering the prize!!!
the current number of tickets to win the Lambo which is worth $200k (~24BTC) is 5.2 million. then which had the highest prize for last round at 0.3BTC had 245 million tickets!
that is a gigantic difference, you can get a much higher chance of winning a much bigger prize in their Golden ticket section.
