There are fresh news from us bonds market.US bonds has broke support level,will be sell off,dollar will goes down and sell offs on stocks will begin,ood of money will looking for new investments,so if small part of that money will come to btc will be btc hossa,do not forget about french elections it may shake Europe
Professional money might have flown into Bitcoin if we had one of the ETFs approved. They are looking for a way to benefit from Bitcoin's potential, without actually hodling Bitcoin. ETFs are perfect for that.
These high level investors aren't really interested to buy themselves into Bitcoin through exchanges. They are looking for a professional platform that suits them, and one that is being watched by the SEC.
the "professional money" as you call it, will come into bitcoin if it wants to and it always does it when it is smart (meaning while there is a dip like when it went down to $900 or when it was $450 or better yet when it was $200).
and from what i understand from ETF, you don't invest money in bitcoin you invest money in ETF and buy something like shares from that ETF and that has nothing to do with bitcoin.
although as i said this before, ETF approval could have been a good positive news for bitcoin.
