Bitcoin as a concept to be improved is interesting, but trusting in a prototype currency whose designer(s) refuse to expose who they are (Satoshi Nakamoto is a pseudonym) is somewhat suspicious...
The whole mining business reminds me of a Ponzi scheme. At the beginning coins could be mined relatively easily (aka packing "freebies"), but then mining difficulty becomes exponential requiring for more dedicated and expensive watt-wasting hardware to get less for more, akin to needing more suckers to get less yield until mining becomes unprofitable and the currency supply stalls without even ensuring it's enough for an actual economy.
