For me I rather chase a smaller prize that hits more often.
But I guess some would always dream big and look for more.
Chasing a smaller prize hitting more often sounds more attractive to me too, it does not feel as good as a big win but at least you know you can hit it and will likely hit it a couple times.
So why not make it 2 btc? and obviously even harder to hit.
for many a 2 btc hit is a huge life change.
Even 1 Bitcoin is enough to change the life of somebody from a poorer country. It can be a large house in many countries.
I suppose while it is a giant prize, it is not going to be as attractive to so many players. I mean. A million sounds even better, but I would rather throw my money at a big win with better chances than basically play lottery.
