Recommendation

Digital currencies are thriving, as advocates, traders and investors use them for speculation and as inflation hedges and fiat currency alternatives. Would-be investors might benefit from a blockchain-101 tutorial, and that’s what technology editor Charlotte Wu offers in this primer examining distributed ledger operations, transaction processing and other details of the crypto ecosystem. Cryptocurrency enthusiasts and new entrants into the world of digital tokens will find this a basic but useful reference guide.
