Twitter adds tipping with Bitcoin after turbulent week for crypto markets

Crypto at a glance

It was a week in which Bitcoin and other cryptocurrencies once again appeared to be trapped in lockstep with the traditional markets, vulnerable to the same supply chain shocks and economic mismanagement as the S&P and other indices.

But, as the week draws to a close, a timely reminder to zoom out and look at the big picture courtesy of bull of bulls, Twitter CEO Jack Dorsey.

The week began on a sour note, with the Evergrande saga threatening to sink the global economy into chaos–and drag Bitcoin with it. As the property giant’s debt problem spread like squid ink in a bucket of water, it again raised the spectre of the market crash last year as Covid-19 lockdowns swept the world, and Bitcoin plunged from $8,000 to $5,000 in a matter of hours.

The cryptocurrency appeared for months afterward to be bound inexorably to the fate of the wider markets, seemingly ending the ‘store of value’ narrative until, finally, it broke free and began its steady rise to the levels we see today. Levels that saw this Monday’s crash from $47,000 to $42,000 seem like such a big deal, despite it still being a 300+ per cent increase on the price this time last year.

But, this Thursday, we got an excellent reminder that, while it might be easy to fixate on short term price movements, this is a long-term investment and people with real vision around the world are building a financial future with Bitcoin at the heart.

After months of hints from Jack Dorsey, Twitter announced yesterday that it is adding, with immediate effect, the ability to pay other users with Bitcoin through its tipping feature. Users around the globe will also be able to post their Bitcoin wallet directly into their profile.

Dorsey has long been one of Bitcoin’s biggest advocates, with his payment giants Square and CashApp having last year integrated the cryptocurrency into their offering.

In the past, Dorsey has said that the cryptocurrency has the power to “unite the world” and bring about world peace.

‘Remember to zoom out’ has become so overused as to be cliche, the desperate clarion cry of the Bitcoin bull when the markets plunge. But if world peace isn’t the kind of big picture vision you want to zoom out and see, with people like Jack Dorsey building it, it’s hard to know what is.
