A true Bitcoin investor will not be happy, if a Bitcoin ETF is approved, because this will only create massive volatility in this market. You will find that the institutional investors will manipulate these Bitcoin ETFs with large capital reserves and you will get massive spikes and huge dumps, which will destroy the use case for Bitcoin to be used as a currency.
Some people rejoice about the SEC's decision to deny the Winklevoss's ETF, because they know it will destroy Bitcoin as a viable payment option.
As a true bitcoin lover I don't want ETF to get approved on bitcoin after read your suggestion.

Already the volatility of the itcoin is the reason that bitcoin to be used from currency so imagine what will happen it will be used only for dumping and bumping from big investors then the future or the bitcoin will be uncertain.
I agree. I dont see any good coming from the bitcoin ETF as such. It will truly disturb the market and give small players less scope to make major profits
