I suspect you're right--and I suspect we may instead have a significant correction (and a liquidation of many leveraged long positions).
Too many significant $1M+ predictions, and that kind of thing frequently is a warning sign...everyone looking for a "quick win" may be surprised here.
I can see a correction down to $33,500 in the cards, with many poeple getting rekt if they're using leverage, and other "traders" will panic and jump ship, affording inexpensive BTC for Blackrock and others.
HODLers will be ok...long term the ETFs will raise the price of BTC significantly, but folks will need to ride out the dip (and/or have the hutzpah to buy the dip) in order to profit.
Stay strong my friends....
