American Bitcoin Corp has attracted attention since launching with backing from Eric Trump and Donald Trump Jr., positioning itself as a public vehicle tied to Bitcoin mining and infrastructure. UBS’s inclusion of ABTC in its portfolio adds another major financial institution to the list of investors with exposure to the company.The 13F filing does not indicate a broader shift in UBS’s cryptocurrency strategy. Instead, it reflects routine equity positioning within a diversified portfolio. Even so, the move highlights how traditional financial institutions are gradually increasing their exposure to companies operating in the digital-asset sector.Bitcoin Slips Below Short-Term Trendline as Weekly Chart Points to Nearby SupportMeanwhile, Bitcoin has lost its short-term trendline on the weekly chart, signaling a clear technical break after weeks of slowing momentum. The new structure shows the candle closing beneath the purple line, which previously guided the uptrend since mid-2024.Bitcoin Weekly Trendline Support. Source: Trader TardigradeThe breakdown places attention on the longer-term trendline that sits just below current price levels. This black line has acted as a major support zone across multiple pullbacks over the past two years, and the chart now shows price moving toward it. Traders often watch this level closely because it has repeatedly attracted new demand during earlier corrections.At the same time, the weekly structure still maintains higher lows on the broader trend, meaning the longer-term line remains the more decisive support for the current cycle. As Bitcoin approaches that area, the chart suggests a potential stabilization zone rather than an immediate continuation of the decline. The reaction around this support will determine whether the structure recovers or confirms a deeper retracement.Wall Street’s biggest Swiss bank and Bitcoin’s chart are flashing fresh signals at the same time.
