If it's true that you actually have a prize of 50 BTC, that would be pretty amazing to win.
Is there any way you can prove that you actually have 50 BTC?
Perhaps sign a message with the adress you have the 50 BTC on?

Sign the wallet is not enough, even if he got that much bitcoins how he can guarante the payment will happen? The only way would be that he put the funds in escrow and i doubt he will do it so play at your own risk even if it's free
Not enough but at least we are sure that OP really holds BTC50 directly at his own wallet so sign message is mandatory here as a start of proving legitimacy. Next one should be what is the assurance that they will pay.
That's why Im agree to poster Patatas above, since the task is so damn hard (at least for me), let those people who will crack a few also given a reward. So splitting the prize is a must here.
Well, I know friends who told us at the beggining of BTC... it will never grows to 3.000$ ..
Everything (rules, etc.) is explained on the website. You may consider that the only risk you take...is to lose time in trying to solve enigmas. Remember an important point: it's completely free..
Have fun.
