Another good way to get a quick handle on what the crypto market is doing is by paying attention every day to the Market Cap (
CryptoCurrency Market Capitalization) as shown at the top of the
CoinMarketCap homepage.
Today it is around $133B (133,268,725,237 billion dollars), which by itself that number is useless. But if tomorrow the number is $140B or maybe $125B you'll know if things are up or down, and how much, before ever even seeing any single coin's price.
Also since I knew the Market Cap was down by around $10B from a couple days ago, it was no surprise at all to see that all coins had a down day.
And if you don't spend everyday on coinmarketcap, remembering the last MarketCap will help to catch you up quick after a break.
