The second week of October has been exciting for the cryptocurrency markets. Perhaps the biggest news is that the Coinbase exchange announced it is listing the 0x token (ZRX) on October 12. ZRX is a protocol token for a decentralized exchange platform that aims to tokenize value. ZRX will be able to be traded against US dollars, euros, and Bitcoin (BTC) on Coinbase Pro's order books. US traders except New York residents will be able to trade ZRX. The price of ZRX jumped 13 percent on the news. Coinbase will transition to full trading capabilities over time.

Here is the rest of the week of review:

Viabtc conducted the first major initial coin offering (ICO) on the Bitcoin Cash (BCH) blockchain and raised over $30 million in 3 hours on October 8. The startup solicited funds for its Viabtc token (VIAT) that will be used as gas and a value transfer mechanism. The token will be able to pay for Viabtc services like mining accessories and exclusive customer support. VIAT will first start trading on the Coinex exchange against USD Tether (USDT) for about 4 cents a coin. Coinex users who trade VIAT will receive an airdrop of the CET exchange tokens.

Gary Cohn, the former chief economic advisor to US President Donald Trump, joined the American blockchain startup Spring Labs. Cohn previously worked at Goldman Sachs (GS  ) for 25 years and left to join Trump's team. He pushed for tax and regulatory reform before resigning due to the controversial trade war policy. Spring Labs is working on Spring Protocol, a blockchain product that will enable information exchange without sharing the underlying source data. Spring Labs CEO Adam Jiwan expressed excitement at working with Cohn.

St. Regis Aspen recently closed its token sale and raised $18 million on the Indiegogo crowdfunding platform. The luxury resort company offered ERC20 security tokens for sale at the price of $1 to accredited investors. The Aspen coins represent an indirect equity ownership stake in the St. Regis Aspen Resort. The tokens are backed by shares in Elevated Returns, a real estate investment trust that owns the resort. The ICO marks an important milestone in the tokenization of real assets onto blockchain.

Crypto prices tumbled this week, down to the $200 billion level. In the top 100, the biggest losers are Global Currency Reserve (GCR), down 43 percent, Bytecoin (BCN), down 38 percent, and MOAC (MOAC), down 26 percent. The biggest winners are Vitae (VITAE), up 199 percent, GoChain (GO), up 35 percent, and PRIZM (PZM), up 30 percent. Traders will watch whether support at the current critical level holds for a bounce.
