5 Lessons from the Great Stablecoin Shift

1 week ago | weissratings.com | Jurica Dujmovic

A few weeks ago, I called stablecoins the “quiet giants” of crypto. That’s because on-chain activity for stablecoins reached all-time highs in March 2025, with market capitalization reaching over $230 billion. Industry forecasts from VanEck suggest daily stablecoin transfers could hit $300 billion by December. That’s roughly 5% of the volume processed by major traditional payment networks and significantly higher than the $100 billion in daily transfers seen in 2024. Source: VanEck.
Level Up to Layer-3s

First, there were Layer-1 blockchains. Also called a “base chain,” this is the primary blockchain for a network. Blockchains like Bitcoin (BTC, “A-”), Ethereum (ETH, “B+”) and Solana (SOL, “B”) are Layer-1s. Then, the previous bull market saw the rise of Layer-2 blockchains, or L2s. Built on top of Layer-1s, these “side chains” are scaling solutions designed to help increase the network’s throughput.
Microsoft is quietly using DeepSeek's technology. What that means for AI stocks.

By Jurica Dujmovic Microsoft's diversification from OpenAI speaks volumes about the future of AI investing When I wrote about DeepSeek's remarkable AI breakthrough in January, I didn't expect to see my predictions validated so quickly. Yet here we are, barely three months later, watching Microsoft Corp. (MSFT) - OpenAI's primary backer - strategically recalibrating its data-center approach in favor of a more distributed, efficient infrastructure.
Opinion: Microsoft isn’t abandoning OpenAI, but it’s definitely cozying up to DeepSeek

Crypto’s Quiet Giants Could Be the Big Brother of the Blockchain

And both the Visa/Worldcoin stablecoin and CBDCs enable the potential for mass surveillance under the marketing banner of "preventing terrorism and money laundering."There are some minor differences between them, of course. Unlike CBDCs, stablecoins can currently be self-custodied in soft wallets like MetaMask or hardware wallets. That means they are stored beyond the reach of governments and can be traded peer-to-peer without oversight. This is a freedom that CBDCs likely wouldn’t permit.

For those keeping score at home, this follows the Merge, Shanghai, Cancun and Dencun upgrades. These continuous improvements show Ethereum's commitment to innovation and user experience. Unlike some blockchains that promise the moon but barely take off, Ethereum's methodical approach to evolution has kept it at the forefront of smart-contract platforms. Even with the occasional hiccup. Fidelity Enters the Digital FrontierWhat happened: Fidelity Investments began testing a dollar-pegged stablecoin.
3 AI Blockchain Projects for Your Watchlist

1 month ago | weissratings.com | Jurica Dujmovic

Last week, I introduced you to the latest evolution in blockchain technology: a cutting-edge new consensus mechanism called Proof of Intelligence, or PoI. To recap: Instead of the complex algorithms used to validate transactions on that blockchain, PoI mechanisms validate blocks by working on actual AI problems to train machine learning models, optimizing algorithms or processing AI datasets. Your hardware still validates transactions and secures the network.
Proof of Intelligence: AI on the Blockchain

The Challenges (Because Nothing Good Comes Easy)Before you sell your Bitcoin to go all-in on PoI tokens, let's talk about the hurdles. Because — as is typically the case for new technology — there are a few notable ones. Complexity & Accessibility Issues: First off, this isn't your average mining operation. Unlike traditional mining or staking, where pretty much anyone can participate, PoI requires validators to have a level of understanding of how AI works.
The Leader of the Web3 Revolution … Is TikTok?

1 month ago | weissratings.com | Jurica Dujmovic

Let's address the privacy concerns that have politicians around the world clutching their pearls: TikTok's data collection practices. As I said, web3 could actually solve many of these problems. Decentralized identity systems would let users control their personal data instead of handing it over to ByteDance. Zero-Knowledge proofs could verify users without exposing private information.
