according to on-chain analyst Ai Yi (@ai_9684xtpa), the ETH/BTC exchange rate has been rising for five consecutive days, currently at 0.037. The last time it reached this level was during the uptrend in January this year.
It is worth noting that a trader lost $22.45 million by longing the ETH/BTC exchange rate last year. The trader longed from 0.055 all the way to 0.03596 before giving up, persevering for a year. Currently, the exchange rate has returned to the level at which the trader gave up.
