The Year of Second-Layer Protocols? Although there are relatively few ‘real-world’ places to spend Bitcoin, congestion on the BTC network is currently impairing its utility by raising transaction costs and reducing completion times. Operating close to its maximum of transactions a second (tx/s), fees have risen as a percentage of each transaction. As it is less congested, transaction fees for the Ethereum blockchain are significantly lower. However, the Ethereum network is still limited to only 20 or so tx/s; as this limit approaches, we think that fees will rise and utility decline. 0% 20% 40% 60% 80% % Jul Oct Jan Apr Jul Oct Jan Apr Jul Oct Jan Apr Jul Oct Jan Apr Jul Oct Jan Apr Jul Oct Jan Apr Jul Oct Jan CNY EUR GBP JPY USD Others
