I have the weekly ETH:BTC chart here since 2015. In the last bull market ETH outperformed BTC from late 2015 to mid 2017 as the ratio rose from 0.00137 to 0.15297. I have shown what I think that 12345 impulse wave looked like. From mid 2017 to now, the ETH:BTC ratio has been in a bear market. I have shown the ABC projected pattern with a C wave ending probably in about 2 months or so in Oct 2019. I think by then Bitcoin might be hitting a new all time high above $20000. That's when many analysts believe an alt season will start (when BTC makes a new ATH). Since ETH is the biggest market cap alt, examining this chart could help to determine when the C wave will end and a new bullish impulse wave will start.
