If you imagine crypto-currencies are the future this has not been a good 7 days. The worth of Ethereum, Bitcoin's principal rival and "the long term of crypto" not so lengthy back, has lurched ever reduce and is now 80% below its peak.
Meanwhile, US regulators have acted towards firms included in crypto-currencies and first coin choices (ICOs) - schemes to generate new cash.
But hope springs everlasting, and in recent days equally a London art gallery and a Scottish resort have contacted me about strategies to allow their customers to spend with crypto-currencies.
So on this week's Tech Tent we discussion this issue: has crypto-forex peaked or do its greatest days lie forward?
We invited David Gerard, creator of Assault of the 50 Foot Blockchain, a very sceptical just take on the crypto landscape, to debate with Christopher Shake, the director of that London gallery, The Property of Fine Artwork.

The gallery's press launch had boasted that it was about to run "the really first artwork exhibition only available through crypto-forex".
By the time Mr Shake arrived in our studio that experienced transformed a bit - customers would be inspired to purchase the 500 works in the October exhibition in Bitcoin or a selection of other electronic currencies but if they desired to use very good previous-fashioned dollars or lbs ., this kind of payment would be recognized.
"Our principal objective is to help and advertise our artists," he says. But as a crypto-currency enthusiast, he explains that there is also issue he desires to fix: men and women sitting on huge crypto belongings are not ready to invest them.
"If a lot of retailers do jump on and accept crypto-currencies, that will insert confidence to the industry," he describes.
But David Gerard says factors are shifting in the opposite route - fewer retailers are accepting crypto-currencies due to the fact they are so risky and the assure of smooth cost-cost-free transactions has proved illusory.
He says several left throughout the 2017 Bitcoin bubble. "You could not have faith in it for volatility, you couldn't believe in it simply because transactions had been slow and typically failed to go through at all. It really destroyed the use-case for the general merchant acceptance of cryptos."

The banking institution has not been rocked by crypto-currencies in the way some envisioned
He sums up his check out of the whole crypto marketplace: "It really is not truly very exciting or shiny any more."
But Christopher Shake sees it extremely in a different way. He promises that everybody from Goldman Sachs to Amazon and Fb is now shifting into crypto-currencies - one thing David Gerard suggests just isn't really the scenario - and he thinks it is an notion whose time has arrive.
"It is sticking close to because it has worth. It is sticking all around since it really is a wonderful engineering, and that's why establishments are receiving into it."
But for all his reservations, David Gerard does not anticipate Bitcoin in specific to disappear in a hurry. "Bitcoin has expended its entire existence lurching from disaster to crisis, any of which would have killed a sane monetary instrument," he claims. "But Bitcoin is a lot more of a robust cultist advocate factor for people who are into it."
His forecast is that crypto-forex will slowly and gradually grow to be far more regulated and normalised - a instead different vision from that of the early Bitcoin advocates, who noticed it smashing the technique and making central banking institutions and governments irrelevant.
Also on this programme, we appear at Apple's new well being-focused View and ask whether or not doctors will be flooded with sufferers anxious about what its ECG check is telling them. And we get two opposing sights on regardless of whether the EU's proposed new copyright regulation is great for artists or will guide to a censored world wide web.
