So lets say 5K satoshi is a realistic price prediction. This entails the marketcap would be about 4,100BTC, this translates to a little over $43 Million.
This would put Golem at number 11 on the coinmarketcap list and would put it at about half the total market cap of MaidSafeCoin. I would say this is a
realistic prediction in the medium term.

So lets look at the 50K prediction: 820,000,000 Golem x 50K Satoshi = 410,000BTC = $430.5 Million
This would put it at number three on the coinmarketcap list, third only to Ripple and Bitcoin. Do not honestly see that happening.

Now if we are talking pure pie in the sky speculation; it could outpace Bitcoin since it isn't actually intended to be a currency but a purchasing token primarily for
CGI rendering, but that is a billion to one chance.
