The Q1 2015 State of Bitcoin report highlights a decline in Bitcoin's price amid demand-supply imbalances, with significant venture capital investments reaching $226 million for the quarter. While Bitcoin's market capitalization fell by 21% to $3.4 billion, the number of Bitcoin wallets surpassed three million, and merchant adoption faced challenges due to Bitcoin's perceived value. Regulatory improvements and increased VC investments have contributed to a more confident industry outlook despite ongoing issues in the mining and exchange sectors.
