I'm still as confused about crypto as I was in 2012
Its extremely simple,
You buy a coin
From there, it's like any other investment. Sometimes you buy a coin to fund a company, sometimes you buy a coin to make faster purchases, sometimes to hold the coin and increase your cash value on it, sometimes buying the coin gives you access to certain incentives from the company that created it. It's nothing new, well mostly (besides shyt like exhanges and yield farming etc).
It's basically what you and humans have been doing our whole lives but now in a more robust digital format vs. being a slave to a bank.
