Ether made an impulsive move up to $462.49 (Coinbase ETH/USD) last night, but it's not the first time we've seen a move like that in the last couple months.
Last night's move up could be the start of another ABC up, 12345 down. We've seen it several times already since we hit $828.97 on May 6, 2018. If it is the start of an ABC, then the C wave may take the price to $475-$480 before a 12345 takes it down to $400 or lower.
I’m no expert and this isn’t financial advice
