Nasdaq is a good addition to bitcoin cause it will further promote and invite institutional investors to crpyto currency also they can easily buy bitcoin with uncomplicated user interface cause in the past it was a pain to bought btc's, now with a fiat exchange adding bitcoin to their company. Ordinary investors and average joe's can have btc or other altcoins.
Nasdaq will also bring is new volume and capital and this is what is required to move bitcoin up further. Nasdaq is a very big platform and it will bring big boost in bitcoins.
The future of cryptocurrency exchanges, when large platforms (for example Nasdaq ) will open the possibility for hedge funds to buy cryptocurrency from them in absolutely usual conditions?
1)Nothing will change?
2)Only "small traders" will trade on cryptocurrency exchanges"
3)Only the largest crypto-currency exchanges will remain and create conditions equal to the conditions of large platforms. No wonder binance is trying

4)Your thought?
I cannot say exactly what will happen with existing exchanges but cryptocurrency trading will become more difficult...
But I see there one positive sign - maybe technical analysis will become more accurate.
Technical analysis is still valid these days however many people think that bitcoins and crypto currencies follow the news and their movement more depend upon the news rather than T.A.
