All cryptocurrencies are down again today. When I say all I mean all. Bitcoin (BTC) is down from $10K to just over $7K and Ethereum is down from $1,000 to $700. However, I do not believe price matters with cryptos, it's how much it is being used that matters. This week I bought PICO-8, books from HumbleBundle and Celeste using Bitcoin, proving the myth that "you can't buy anything with Bitcoin" is false. With the Lightning Network coming to Bitcoin which will hopefully fix some of the issues with Bitcoin like the fees and backlog, things can only get better.
Disclosure: I own bitcoins and other cryptocurrencies.
Authors Note (2/21/2020): cryptocurrency is a meme now.
