bitcoin is problemtic in the mining and the size of its blockchain because not all the people could be have the file in their own computers, then in the long run the system will tend to transform in something centralized,
The blockchain size is currently about 7 GB, with only 100.000 bitcoin accounts, something insignificant to the global economy, still insignificant for a little country of third world. What will happen when exists 10 , 100 or worse 1000 million of accounts, what will be the size of the blockchain file?.
