The first week of November has been exciting for the cryptocurrency markets. Perhaps the biggest news is that Coinbase announced it will add the Basic Attention Token (BAT) to its trading platform. The Coinbase exchange has added support for browser company Brave's BAT starting this weekend. Customers who don't reside in New York will soon be able to transfer, deposit, and post limit orders before full trading begins. Coinbase also aims to create a BAT/USDC trading pair on its order books. The price of BAT jumped 28 percent after the announcement before settling down some, and volume on the Binance exchange rose. BAT is the third token Coinbase listed this year.

Here is the rest of the week in review:

The controversial company Tether, which runs the stablecoin USDT, released a contentious letter to bolster its reserve claims. The short letter by Bahamian bank Deltec dated November 1 stated: "The portfolio cash value of your account with our bank was US$1,831,322,828." But the lack of a name attached, a strange signature, and a liability caveat spurred many in the crypto community to criticize the usefulness of the letter. Some also criticized the choice of Deltec as a bank due to the Bahamas' shady past. Tether has yet to complete a full audit of its dollar reserves.

Startup Stably launched its StableUSD (USDS) stablecoin for purchase and redemption. The real-time token is supposed to be backed by US dollars held in escrow by a regulated Nevada trust company. An accounting firm will also perform weekly attestations for Stably's fiat reserves. The tokens are generated through smart contracts and require know-your-customer compliance. This year, the market for stablecoins has become increasingly saturated as startups raise more funding for transparent, regulated, and collateralized stablecoin projects.

Bithumb and seriesOne are teaming up to launch a security token exchange in the US. The South Korean crypto exchange and crowdfunding platform issued a press release that they are building a product that will allow companies to tokenize major assets like equity and debt. The project awaits approval from the US Securities and Exchange Commission and the Financial Industry Regulatory Authority (FINRA). The two companies believe that a compliant security token exchange will be in demand in the US.

Crypto prices remained fairly stable at around the $210 billion level. A weekend selloff threw Bitcoin (BTC) toward $6,200, but a late rally to above $6,400 rallied the rest of the market. In the top 100, the biggest losers are Neblio (NEBL), down 22 percent, SmartCash (SMART), down 18 percent, and GoChain (GO), down 17 percent. The biggest gainers are TokenPay (TPAY), up 51 percent, BOSCoin (BOS), up 48 percent, and Vitae (VITAE), up 33 percent. Maybe the new month will produce some news that moves the markets more.
