What is Exchange Traded Fund:Exchange Traded Fund most like stock exchange. Those fund use to be traded on stock exchange that's called EFT. From ETF you can track all tradable assets and you can trade from there. That means you can track price buy and sale to other investor through stock exchange.
ETF become most popular due their low cost facility. There is many broker for buy sale assets. I just share my basic idea about ETF. If you want to know more details please visit

How will be benefited crypto or Bitcoin holder's from ETF:If U.S. Securities and Exchange Commission (SEC) approve EFT application than many big investor will start invest on Bitcoin/crypto-currency. Because Bitcoin or other crypto-currency will consider like an asset. So crypto currency will be open diverse set of investors. There will be no restrictions for crypto currency. For that reason crypto currency price will increase rapidly. Those will buy Bitcoin or other crypto-currency they can track real time price from ETF and can sale to other investors.
However, what I understand that if SEC approve EFT than crypto revolutions will be unbelievable. Most of crypto currency will be up trend. We can see currently just discussing about EFT on SEC board & price of Bitcoin on bulls run. We expect SEC will consider EFT application on middle of August.
