Coinbase
Definition
A leading cryptocurrency exchange platform founded in 2012, allowing users to buy, sell, trade, and store digital assets like Bitcoin and Ethereum with fiat currency.
In blockchain technology, the 'coinbase' transaction refers to the special first transaction in a block that delivers the block reward to the miner, often including an arbitrary message.
Slang in crypto circles for the moment you cash out gains—or more often, watch them evaporate—on the aforementioned exchange.
Examples
I dumped my entire portfolio on Coinbase right before the bull run kicked off—classic me.
His coinbase transaction included a cheeky message: 'To the moon... or at least to pay rent.'
Grandma thought Coinbase was a fancy jar for her couch coins; now she's HODLing Ethereum.
After Coinbase's latest fee hike, even my digital wallet feels lighter than my actual one.
