Binance's own trading data since launch tells the story:

$BTC Aug 17, 2017: $4,261 → Today: $83,171 (19.5x)
$ETH Aug 17, 2017: $301 → Today: $2,550 (8.5x)
$BNB Nov 6, 2017: $1.50 → Today: $769 (513x)

The exchange token massively outperformed the majors. $BNB's 513x is partly due to its utility mechanics—trading fee discounts, burn mechanism, and ecosystem expansion into BSC. Classic case of platform growth directly feeding token value. If you held the house token instead of just trading on the platform, you won 26x more than $BTC holders and 60x more than $ETH holders over the same period.
