i think the money is still out of market because market value is still low and when we can remember value of market while bitcoin was 20 000 dollars we can understand that big money still out and it is waiting to come back the market again i think one day the big money will start to enter the market and we will see new high value in market.
Obviously there's no money in because all the price is still down as compare to last year. The only thing that will bring the influx of new money to the market is a Bitcoin ETF but it's still out of the equation because SEC hasn't yet decided the faith of Van Eck/Solid X Bitcoin proposal. So what we can do is wait and see how everything goes in the next coming months.
Basically Bitcoin ETFs are securities, which can be sold/bought through stock exchange companies. However ETFs are offered for all asset classes both traditional investments and alternative assets such as commodities or currencies. The main benefit of ETFs is to eliminate investor needs to register on the exchange or wallet. I think waiting might be the only best way.
