hello friends here is my new blog in simple words about ETF (exchange-traded fund) 
we can say its a legalize regulated body where from the stocks ,bonds, commodity etc are trading on markets ,and S.E.C(security and exchange commission) approves this.
Perhaps you should know that last year the C.B.O.E (Chicago Board Options Exchange) had applied to S.E.C approval for Bitcoin ETF contract but the S.E.C had rejected last year,Because at that time S.E.C did not understand that the BITCOIN has a utility token or a commodity token or a security token. but the manner in which it has been requested this year, the experts are saying that this year's approval will definitely get And quite a lot can be good in it.
If bitcoin gets approved at ETF then we can get a very good result from it, as 10% of all the stock markets traders have not even invested in bitcoin because none of the bitcoin A liaison institution does not regulate it in this way,
The ETF is a regulatory board that trusts the investor who has the approval shares to which they can trade in the stock market. What will happen to it? If the ETF comes in biTCoin, people will invest in it with confidence and I think Bitcoin can come in a large amount of investment.
And some experts have even said that till December 2018, the rate of bitcoin can be up to $60000.
i hope for it ...
