Ethereum Launches Long-Awaited Decentralized App Network

One of the most – if not the most – ambitious blockchain 2.0 projects to date, Ethereum, has finally launched. Ethereum is aiming to create a new universe of programmable contracts, powered and secured by its own blockchain.

“Don't put a lot of value at risk unless you really, really are sure you know what you are doing, and you're confident about your risk assessment of the network.”

BTC China's Bobby Lee at Rise Conference: 6 years Until Bitcoin is Mainstream

BTC China CEO Bobby Lee and OKCoin Head of International Jack Jiu took to the stage at the Rise Conference in Hong Kong to discuss where Bitcoin was and what’s ahead for the popular cryptocurrency. The two explained to be confident that Bitcoin will go mainstream, although they said it might take a few years.

Taking the stage, Lee explained:

For traders that can mean that Bitcoin is a speculative tool, but as Bitcoin becomes more mainstream that can mean transfers, that don’t necessarily use Bitcoin itself but the blockchain ledger it runs off.
