Over the years we've had so many ETF related news (hype) that got shot down by SEC rejecting them that at this point when people hear any news about another ETF
proposal they are ignoring it. So I think at this point it is going to be like meh, meh, meh, meh, ... holy shit one got approved and bitcoin is shooting to the moon
Jokes aside I still think ETF is terrible for the "decentralized" bitcoin but we also know there are loads of idiots who like to put their money where they can't control. So it looks "lucrative" for them not by nature and consequently it can help the bull run get started.
As for $150k I think it is too much of a lowball, if we start the rally and go beyond the previous ATH and specially if we enter the 6 digits range (ie. going beyond 100k) we can expect a situation similar to the last month of 2017 when price suddenly went from $8k to $20k which is a 150% rise in short time.
