The challenge of safeguarding your private keys and not falling victim to the many fraudulent schemes to separate the gullible from their bitcoin. The wealth concentration resulting from emitting the majority all bitcoin that will ever exist in just the first few years. It's designed not as a peer-to-peer currency but a p2p speculative asset. Leaving just a fraction of a percent of all bitcoin to be mined in the last century (2040-2140) of its emission. And relying almost exclusively on transaction fees to provide security after 2040.
