Introducing the new Blockchain.com monthly newsletter — April Edition: “After the Dust Settles”

The quality of information and data in crypto has improved in recent years, so you may be asking why another monthly newsletter?There are still some big data and analysis gaps in crypto.

PlanB: Bitcoin Needs Only $200M Monthly to Stay Above $7k Level After Halving

100trillionusd, the anonymous creator of the Bitcoin stock-to-flow model has provided new evidence to support the popular opinion that the price of Bitcoin will surge in the months after its historic third halving that is now less than three weeks away. The latest research puts into perspective the amount of cash inflow that Bitcoin has needed to stay above the $7000 level since October 2017, the reward paid out to miners for verifying a block of transactions, and the total number of transactions added to the Bitcoin blockchain monthly.

Talking Digital Future: Smart Cities

My journey into smart cities and their future development was a really big surprise, as the way I arrived there was not something that I had planned. I was working as the chief information officer for a company in Northern California called O'Reilly Media when I got a call from a headhunter who asked if I would consider being the chief information office for the City of Palo Alto. I can vividly remember — it was only about eight years ago — my feeling when she asked the question. The

Market Volatility Continues Amid COVID19 Uncertainty

In times of deep crisis such as this it’s important to stay true to who we are and that seems to get more and more difficult the deeper we get.

Founded in 2011, Silk Road thrived for the next two years until the Federal Bureau of Investigation shut it down in 2013. Authorities later revealed that completely free blockchain explorers aided their investigative efforts.Bitcoin’s transaction ledger is completely open for the

Unsurprisingly, Markets Are Bearish

Out of all the hockey stick graphs we’ve been looking at over the last few weeks, the one that really takes the cake is the google trends chart showing the number of people searching for the term ‘unprecedented.’ The levels we’re seeing at the moment, quite frankly, have never existed before. Demand on telecommunications have been unprecedented. The sudden halt in air and even ground travel is unprecedented. And the actions taken by governments and central banks around the world have been well… unprecedented. We’re litteraly living through history at

How to Trade Bitcoin Using Leverage and Not Worry About Liquidation

Institutional traders have long known the benefits of derivatives trading, including leverage and hedging. By trading options markets, one can predetermine maximum gains and losses, even with volatile assets like Bitcoin (BTC). Despite being far more complex, such instruments allow traders to generate gains independent of what happens over the next weeks or even months, which is essential for traders’ peace of mind to achieve optimal performance.Retail traders have only recently begun using derivatives, although they have focused almost exclusively on futures contracts offered by BitMEX, OKEx, Binance and so many
