So if you had a supercomputer you would basically create a pool of your own resources, but no-one has that much hash - So why not join a pool and build a supercomputer together?
To me, cracking the puzzle is not really about the prize but I find it exciting to see how long it takes and what methods people use to crack it. like picking a lock. Plenty of people pick locks as a hobby
For me the prize is the main, considering that i am investing money (actually around 400$ for hardware) and electricity costs (in Italy 0,55$ kilowatt/hour) in the challenge so a pool is not a good investment, the prize is too small.
Of course the glory of finding the key is nice and funny too but secondary.
I like to pick everyday the keyspaces to analyze randomly, it's a way to see how the random choice progressively cover the entire puzzle 66 keyspace. For me it's very interesting.
Dividing the keyspace in 74 million parts it's like to meet a person in a country with 74 millions people. With 7,4 million parts it will be like meeting the person in a big city.
