Today I learned that Bitcoin and Dogecoin are the only coins in Top 10 that weren’t premined and distributed amongst buddies

Okay, this will spark some controversy. I'm prepared to be called names.

Bitcoin: no premine, no ICO. Satoshi gave everyone a 2 months notice before the network went live so everyone started mining on an equal playing field.

Ethereum: premined. ICO. 72 million of the current 116 million Eth has been premined and sold by the founders.

Binance SC: preminted. ICO. 40% went to the devs, the rest was sold.

Cardano: preminted. ICO. 16% went to the dev companies, the rest was sold.

Ripple: 100% premined. Gradually being released into the market by founders and investors.

Dogecoin: no premine, no sale LOL

Polkadot: preminted. ICO. 50% of the initial supply was sold.
