A brief summary of major events over the last week:
Cryptohackers community RaspiBlitz released a Bitcoin Lightning node that runs on a Raspberry Pi microcomputer. Following their guidelines now everyone can assemble a Bictoin payments terminal for $100 in hardware.
Ethereum keeps up with the updates. Constantinople network update is scheduled to be mined in a 7,280,000 block. This update delays the difficulty bomb for one more year. Also the update reduces mining complexity and mining rewards. The total miners reward for the work done is the same, but the network consumes less power.
Spike of the week: almost unknown Enjin Coin has trippled its value over one day and rushed in top 100 of cryptocurrencies. It's a common ERC-20 used to trade items in several online games in Asia.
