Most, if not all, financial institutions aren't exposed to cryptocurrencies directly either through futures or the underlying currencies. Institutions are defined as endowments, sovereign wealth funds, pensions and asset management firms such as Goldman Sachs. Capital inflow into the cryptocurrency space in aggregate is still less than $10B. If the Norwegian sovereign wealth fund bought Bitcoin, their minimum purchase would probably be $50MM which represents .5% capital inflow and a nice uptick in "market cap" of the industry.
Bitcoin is by no means established because these institutions aren't investing. If and when the day comes that this happens then Bitcoin will be established and increase one or two magnitudes. Many of the above institutions legally can't invest because they are restricted by their mandates. Bitcoin is a terrible use case for criminals because it's transparent. Monero would be better because it's anonymous.
