I have been using ETF's for as long as they have been available, including leveraged inverse ETF'S, to help me with my investment goals. I can find nothing comparable to replace or substitute for them if they go away. I don't understand why these funds are being singled out among all of the myriad other investment products, many with far more dangerous traits and risks. Products that I have been using for well over a decade could soon become unavailable to me or anyone else for that matter. At the very least, their use should be grandfathered for those of us that have used them for many years and have the highly restrictive regulations that are being proposed be applied to that are new them.
