People tend to innovate and if these platforms cant offer new advantages, they will certainly die.
It is complicated because you can do everything and lose all trading volume "Nokia" or do nothing and still wanted "Blockchain.info"
One of the start-ups to look out for is BLOCKCHAIN BOARD OF DERIVATIVES, the platform combines both centralized and decentralized features of Blockchain to stay aloof the crowd in the space. This is an all-in-one trading platform, that is going to be welcomed when it is launched.
I do not have any information about that platform but their idea seems good.
I think the future of platforms that allow you to have a cold store of your cryptos plus the possibility of exchange "linking hardware wallets and trading platforms."
