US President Trump said that he will definitely implement tariffs on Canada during a conversation with Canadian Prime Minister Carney. "We had a very good conversation," Trump said, "I believe that the issues between Canada and the United States will be resolved smoothly," he added.

A segment of the Ethereum community is urging the Ethereum Foundation to make decisions that could potentially disrupt the entire social structure of the smart contract network by imposing restrictions on Ethereum's layer-2 (L2) networks, as stated by Polygon co-founder Sandeep Nailwal. Nailwal expressed his concerns during an episode of Cointelegraph's Chain Reaction show on March 28, highlighting the pressure and negative sentiment towards L2 networks during the current market cycle, particularly with the subdued price action of Ether (ETH). Emphasizing the importance of Ethereum's survival for the success of layer-2s, Nailwal cautioned against pressuring developers based on short-term price movements, as it could lead to decisions that harm the social cohesion of Ethereum. The Polygon co-founder commended Vitalik Buterin's leadership within the Ethereum Foundation, attributing him as a key figure in maintaining the unity of Ethereum's ecosystem and attracting talented developers to build on top of the network. Nailwal also discussed the distinction between settlement layers and execution layers in blockchain networks, highlighting the potential for Ethereum's base layer to benefit from the proliferation of execution layers and promote long-term growth and interoperability within the ecosystem.

Bitcoin (BTC) is facing challenges in surpassing the $90,000 mark, indicating a lack of buying interest at higher levels. Concerns surrounding US trade tariffs and inflation pressures are causing unease among market participants. Predictions for Bitcoin's price in 2025 vary, with the most bearish target at $59,040 and the most bullish at $138,617 according to Polymarket data. Real Vision's Jamie Coutts remains optimistic about Bitcoin's potential to reach a new all-time high above $109,000 by the end of the second quarter. Monitoring support levels for Bitcoin and major altcoins is crucial for understanding their price movements.

On the SOL/USDT daily chart, there is a noticeable absence of demand from the bulls, with sellers aiming to push the price towards the $120 to $110 support zone. Buyers are anticipated to vigorously defend this zone to prevent a further decline towards $80. The key overhead resistance to observe is the 50-day SMA at $153, and buyers will need to push the price above this level to signal a potential floor at $110, which could lead to a surge to $180.

Dogecoin (DOGE) encountered negative sentiment as it retreated from the 50-day SMA at $0.21 on March 26. The DOGE/USDT daily chart indicates a period of range-bound movement in the near future, with the price potentially oscillating between $0.14 and the 50-day SMA. A breakout above the 50-day SMA could indicate a formation of a higher low by the bulls, potentially resulting in an increase to $0.24 and later to $0.29.

Cardano (ADA) faced difficulties in maintaining levels above the 50-day SMA at $0.75, leading to profit-taking by short-term buyers. The ADA/USDT daily chart suggests a potential decline towards the uptrend line, where buyers are expected to intervene. If the price bounces back from the uptrend line, the bulls may try to push the pair above the 50-day SMA, potentially resulting in a rise to $0.84 and then to $1.02.

Bitcoin Core version 29.0rc2, the latest update since version 28.0 in October 2024, brings significant changes to the peer-to-peer network, mempool policy, and mining processes. The update also includes new remote procedure calls (RPCs) and updated REST APIs. One notable addition is the introduction of "ephemeral dust" for dust outputs in zero-fee transactions, requiring them to be spent with other outputs in a single transaction package. This release aims to improve efficiency through mempool and mining adjustments. The updated Bitcoin Core version is now available for testing, with enhancements to the wallet and build system, including GUI improvements and a transition to CMake from Autotools. These changes aim to enhance network security and user experience, solidifying Bitcoin's position as a leading cryptocurrency.

 Hyperliquid announced that its blockchain has been upgraded, adding a fully on-chain validator voting function for asset delisting. When there is enough voting support for delisting, the operation will be automatically triggered on-chain. This equity-based permissionless voting weighting mechanism is natively integrated into HyperCore and does not require off-chain coordination.

As a demonstration of this mechanism, validators 2-5 of the Hyper Foundation will vote around 21:00 on March 29, 2025, Beijing time to decide whether to delist the MYRO contract. Validator 1 of the Hyper Foundation will abstain from voting until the completion of the initial delegation plan participants' delegation.

Experienced trader Peter Brandt, with a career spanning over 50 years, has issued a cautionary statement regarding the future of Bitcoin. Brandt pointed out the possibility of a significant decline in the low $70,000 range, citing similarities to a bear flag pattern on Bitcoin's chart. This pattern indicates a potential 15% decrease in Bitcoin's value, with the likelihood of further drops. Despite Brandt's forecast, there is still uncertainty in the market, with some analysts suggesting Bitcoin could surpass its current price levels and reach $91,000. The future of Bitcoin remains uncertain, and whether or not Brandt's bearish prediction comes true will depend on future market trends.

The submission of this document is a crucial step in the process of proposing a new ETF. Once acknowledged by the SEC, it will be published in the Federal Register, initiating the approval process for Grayscale's Avalanche ETF proposal. Grayscale aims to convert its existing Avalanche Trust, established in August 2024 as a private placement, into a spot ETF with assets exclusively consisting of AVAX, the native token of the Avalanche blockchain network. The investment objective is for the trust's shares to reflect the value of AVAX held by the Trust, adjusted for expenses and liabilities. The Coinbase platform will act as the custodian for the Trust, while BNY Mellon Asset Servicing is designated as the administrator and transfer agent. This filing comes in the midst of a competitive push in the spot Avalanche ETF race, with VanEck also submitting an S-1 registration statement to the SEC seeking approval for a spot Avalanche ETF. Both Grayscale and VanEck are competing to be the first to market with a spot Avalanche ETF. Avalanche is a high-performance Layer 1 blockchain known for its low latency and scalability, consisting of the X-Chain for asset transfers, the C-Chain for Ethereum-compatible smart contracts, and the P-Chain for validator management and custom blockchain creation (subnets). The news of Nasdaq filing for approval of Grayscale's Spot Avalanche ETF was originally reported by Coindoo.

Terraform Labs, the company responsible for LUNA and TerraUSD, will be launching a crypto loss claims portal on March 31 to reimburse individuals who lost a minimum of $100 due to the Terra ecosystem collapse in 2022. Following approval from a Delaware court to wind down operations, Terraform Labs settled with the SEC for $4.47 billion in June 2024. Claimants seeking reimbursement must submit their claims and supporting documentation through the portal by April 30, with preferred evidence being read-only API keys for accuracy. The company estimates potential payouts of $184.5 million to $442.2 million, but the total eligible crypto losses are challenging to determine.

Following a promising start to the week, Bitcoin experienced a shift to negative returns as the price dropped by 3.5% to an intraday low of $84,120 on March 28. The price rejection took place at the intersection of the descending trendline and the upper boundary of the ascending channel pattern. Bitcoin is currently positioned below the 200-day exponential moving average on the daily chart, potentially leading to further downside if it closes below this key indicator. Analysts suggest that Bitcoin may correct to the $72,000-$75,000 range if liquidity conditions remain unchanged, with the Global M2 money supply potentially triggering a rally around May 1. The recent filling of the CME gap between $84,435 and $85,000 could result in a short-term bounce for Bitcoin, but there are warnings of a possible long-term correction leading to new lows in 2025. Traders are closely monitoring key support levels and market structures to determine the future direction of Bitcoin's price.
