+Financial institutions are likely to use crypto in the art of accounting like Tesla did with BTC. Crypto will become a tool to manipulate financial reporting metrics rather than an investment;
As long as it doesn't lead to any regulatory action against crypto as a whole, this is irrelevant to crypto.
+Financial institutions have bought a lot of crypto and they will sell a lot of crypto: this happens when financial institutions want to take profits or offset losses. This sell-off will create a huge drop as ICO projects sold out huge amounts of BTC & ETH in 2018 after successful funding. Financial institutions are not the place to burn tokens ^^
It's stil a net positive, because not everyone will dump, and crypto gains more reputation as a store of value.
By the way, you can't really say that institutions are buying "crypto", so far they only bought Bitcoin and nothing else.
