The evidence strongly supports the statement, although no single source confirms it in its entirety. Multiple high-authority primary sources from Binance itself (how-to-buy guides, price-tracking pages, and Binance Square posts) consistently confirm that the BSquared Network (B2) is a part of the 'Binance Alpha' program. These sources also establish that Binance Alpha is linked to airdrops, with some providing generic links to the 'Binance Airdrop Portal'.The most crucial piece of corroborating evidence comes from a Bitget news article, a credible third-party source, which explicitly states that the Binance Alpha program has launched 'two core high-value' events. While this source doesn't name the specific projects for these two events, it directly supports the claim of a 'second' airdrop or event occurring under the Binance Alpha banner.When combined, the evidence paints a coherent picture: BSquared Network is a confirmed participant in the Binance Alpha program, the program is known to conduct airdrops, and there is external reporting of two major events having occurred. The mention of a 'HAEDAL Airdrop' in another source does not contradict the claim but rather reinforces the fact that the program is actively launching airdrops for various projects. The lack of a single source explicitly stating 'the second airdrop for Binance Alpha was for BSquared Network' prevents a definitive conclusion, but the cumulative weight of the evidence makes the statement highly probable.
