After a rough start to the year, the price of bitcoin is about flat in the last seven days. The largest cryptocurrency by market value is currently trading at $41,671, according to Coin Metrics.
Ether, the second-largest, is up about 2% in the same time frame. It's now priced at $3,113.
Other top coins had a better week. Cardano, Terra and Dogecoin, for example, jumped over the last seven days, Coin Gecko data shows.
Along with price movement, here are six important things that happened in the crypto space last week.

In June, Kim Kardashian posted an Instagram Story promoting a cryptocurrency called EthereumMax.
"Are you guys into crypto???" she wrote. "This is not financial advice but sharing what my friends told me about the Ethereum Max token!" Kardashian included the hashtag "#ad," which indicates that the post was paid for as promotional content.
