ETHBTC is the market for Ethereum paid for in Bitcoin. It provides the long term holder of ETH or BTC the opportunity to move assets in either coin between the two major cryptocurrencies for growth depending on which coin is performing better at any given time with respect to a given fiat currency, such as the US dollar. As such it directly couples the BTCUSD and ETHUSD markets. Given the size of the BTCUSD and BTCEUR markets, the corresponding ETHUSD and ETHEUR markets generally trend with their big and older sibling. The Ethereum community is expecting that ETH will overtake BTC at some point, because of its technical features for trading more sophisticated assets, for example via smart contracts, which are essentially algorithms executed on the blockchain depending on predefined conditions.
In the current bull market, the performance of ETHUSD has been lagging that of Bitcoin/USD, which has already printed a new high since the September correction, while ETH is still close to 20% away from its prior high of just over 4000. The ETHBTC chart shows the reason. ETHBTC is range locked into a converging triangle formation since the Spring 2021 crypto correction. ETHUSD performance cannot improve in a consistent manner until this triangle is completed, and the next leg, the fifth wave of the five-wave impulse has started.
