I would like to raise funds with Etherum and create an exchange traded fund (ETF). People could buy and sell their shares any time on the market. There would be an initial fund raising period where I sell shares. I want to convert the received Etherum automatically to Bitcoin and invest it in the Bitcoin space. Then I would like to pay dividends on the proceeds to shareholders, automatically converting Bitcoin back to Etherum and sending it out to each sharesholder proportional to their investment level. I'm looking for programmatic solutions, with virtually no or very little intermediate fees. Could you please advise how I could do this with Etherum? Thank you for your help.
