It is good and clean, I would change the text though as most people would read it as "Bitcoin Oyster based raffle lottery"...
Bitcoin and based raffle lottery is on the same font, and located towards left.
I read it as Bitcoin Oyster (as the title) and Bitcoin based raffle lottery (as the well.. tagline).
I would rather suggest more space between each words of Based Raffle Lottery. But the current one is quite fine, to be honest.


Anyway, the second entry is great all the same.
