One thing I learned about the Bitcoin ETF denial, and that is Bitcoin does not really need SEC ETF approval to be a stronger currency. What Bitcoin should focus now is the scalability issue so that whenever Bitcoin got to the mainstream, there will be no hundreds of thousands or maybe even millions of transaction being unconfirmed for days. To be approved ETF, SEC requires Bitcoin to be regulated and that is against the reason why Bitcoin is really created.
The point of the Bitcoin ETF is not making Bitcoin stronger but accessible to traders on NYSE NASDAQ just like other commodities, stocks and currencies.
I learned from the Bitcoin ETF denial that Bitcoin is not yet ready to be in mainstream. There are still lots of work to be done, and it should be well regulated in order for SEC to approve Bitcoin ETF. Aside from that I think it depends on the kind of proposal that was submitted to SEC. The proposal should have showed that Bitcoin market can secure the funds that will be allocated to Bitcoin ETF.
Basically, you want Bitcoin to be like Paypal ? Regulations can not stop or block Bitcoin transactions, only prosecute users.
