Di scandal bin shake di confidence in di whole sector.

E bin be like say cryptocurrencies go remain a niche product, with a gingered but somehow limited following.

But just a few months later and di industry come dey buzz with optimism again. Behind di ginger – na di success of Donald Trump for di 5 November Presidential election.

Di feeling na say im go dey more favourable to di cryptocurrency sector and, so far, dat wan seem to be di case.

For early December Trump say im go nominate former Securities and Exchange Commission (SEC) commissioner Paul Atkins to take up di top chairman role for di Wall Street regulator.

Mr Atkins dey seen to dey far more pro-cryptocurrency dan outgoing head, Gary Gensler.

Dat announcement help di value of one bitcoin, di biggest of di numerous cryptocurrencies, rise to $100,000.

“With Trump winning, you fit imagine say in 2025 you go get proactive regulation. You go get removal of some negative regulation, wey go den allow banks and oda institutions into di space,” na so Geoffrey Kendrick, global head of digital assets research at Standard Chartered tok.

In particular, Mr Kendrick point to a piece of guidance issued by di SEC called SAB 121. Since taking effect in 2022, e don make am difficult for banks and oda financial firms to provide cryptocurrency services.

AI don dey get personal – Zoe Kleinman, BBC Technology Editor

As AI tools move into our phones – Apple, Google and Samsung all don launch services wey fit edit photos, translate languages and carry out web searches – we dey for di start of time wey AI go become a key part of our digital lives and e go increasingly dey helpful on a personal level.

Make we take diary management as an example. AI tool fit manage your diary for you, if you allow am to access am. But how far dis one go go?

In order to dey truly useful, e mean say e also need to know who you go rather avoid meeting, or relationships you wan keep secret, and from whom?

AbI you want am to provide you with summaries of counselling sessions, or medical appointments?

Dis na deeply personal information, and fit dey very embarrassing and valuable if some error mean say e dey shared. You fit trust di big tech firms with dat kind of data?

Microsoft don dey push hard at dat particular door. E enta trouble for 2024 for dia demo of a tool called Recall, wey take snapshots of laptop desktops evri few seconds, in order to help users locate content dem don see but no fit remember wia.

Now, dem don make a number of changes to di product – wey dem no even launch – but stand by am.

“I think we dey move to a fundamentally new age wia dia will be ever present, persistent, very capable co-pilot companions in your evriday life,” di firm head of AI, Mustafa Suleyman tell me recently.

Despite di challenges, Ben Wood, chief analyst for technology research company CCS Insight, expect say more personalised AI services go come out for 2025.

“Di output go continuously dey updated by drawing on evolving data sources, such as emails, messages, documents and social media interactions.

“Dis go allow di AI service to dey tuned specifically to pesin communication style, needs and preferences,” e tok.

But Mr Wood accept say letting AI loose on your personal information go be a big step.

“Trust go dey essential,” Mr Wood tok.

Data on di move – Ben Morris, Technology of Business Editor

Di more money dem pour into AI, den di more datacentres go need to dey built.

Training and running AI require a lot of computing power, and dey work best with di latest computer chips and servers.

Over di next five years as much as $1tn fit dey invested in datacentres by di biggest data users, including Google, Microsoft and Meta, according to CCS Insight.

In Europe alone, between 2024 and 2028, data centre capacity dey expected to grow by an average of 9% annually, according to property services company Savills.

But those new facilities dey unlikely to dey built in di current datacentre hubs like London, Frankfurt, and Amsterdam.

High property prices in those cities – Savills say in London land prices fit be as much as £17m per acre – plus tight electricity supply mean say developers go begin look elsewhere.

For UK cities like Cambridge, Manchester and Birmingham fit be home to di next wave of datacentre construction.

Elsewhere, Prague, Genoa, Munich, Dusseldorf and Milan dey likely to dey considered for Europe.

At di heart of some of those new datacentres go be di latest computer chip from Nvidia, di company wey dey dominate di market for chips used for AI.

Di new chip go allow tech firms to train AI four times faster and see AI operate 30 times faster dan current computer chips, according to Vivek Arya, senior semiconductors analyst, for Bank of America Securities.

Nvidia biggest customers, Microsoft, Amazon, Meta and Coreweave dey likely to get di tech first, according to reports.

But oda customers fit struggle to get dia hands on di super chip, with “supply wey go dey limited for 2025”, according to Mr Arya.
