當減半完成時，每個區塊可以開採的比特幣數量將從每個區塊的12.5 枚比特幣變為6.25 枚比特幣，即代表每天開採的數量由每天約1,800 枚減至 900 枚。所以比特幣的產量越少，它就會越稀有。
The single most important issue currently facing the Ethereum network is scalability. The Ethereum network supports hundreds of decentralized applications. This means it needs to process a high number of transactions per second. In a recent speed test, the network only managed 20 transactions per second. By comparison, Visa’s maximum capacity is close to 24,000.
A longer term issue is the sustainability of Proof of Work (PoW) and mining. Because each transaction on the Ethereum network uses about 30 kWh (Kilowatt hours). Furthermore, the electricity used by Ethereum mines could power over 650,000 American households every year.
