Dear SEC,

As an investor in the cryptocurrency area for several years, I can clearly see the progress the industry is making. While there are bad players, Van Eck and Bitcoin are not among them. As time goes on, change occurs more rapidly. This may seem like a premature move to some, but the truth is that it is well overdue. At some point in the future, can you not see a day when electronic currencies are the rule and not the exception? The advantages provided are too extensive for this to not be the case.

Bitcoin is the standout, at this time. Perhaps other currencies will step forward and present better technologies or perhaps Bitcoin will outpace them all as it changes over time. The key is to recognize that the change is here, now. Hundreds of Billions of dollars are being invested in technologies around this technology.

I believe an ETF is overdue. I believe a competitive marketplace should exist with more than one etf allowing investment in Bitcoin, and other cryptocurrencies as they meet some minimum threshold for viability. Bitcoin has been around longer than any of them, and it is mature and ready for further expansion.

Please approve Bitcoin ETFs and give serious consideration to future cryptocurrency etf applications.
