The core of the statement, which is that Gate Alpha launched a points-based airdrop, is strongly supported by multiple high-authority primary sources. Three separate summaries from the official Gate.com domain explicitly confirm the launch of a 'Gate Alpha Points System' or 'Latest Points Campaign' that includes a 'massive airdrop prize pool' and 'airdrop rewards'. Other sources, while less authoritative, also corroborate the existence of Gate Alpha's airdrop ecosystem. However, the specific details within the statement—that this is the '120th' airdrop, that it includes 'tiered rewards', and that it is available on 'multiple chains'—are not explicitly confirmed by any of the provided source summaries. The mention of 'on-chain trading' suggests blockchain involvement but does not confirm a multi-chain approach. While these details are plausible for such a campaign, their verification is absent from the evidence. Despite the unverified specifics, the fundamental claim is true. The lack of contradictory information for the details, combined with the strong, official confirmation of the main event, makes the overall statement highly probable. The assessment is therefore 'likely_true' with high confidence, acknowledging that the central assertion is verified while some of the finer points are not.
