I bought what I thought was a regular Bitcoin ETF. It was helpfully called the Betapro Bitcoin ETF (HBIT). Reader, it was not a regular Bitcoin ETF. According to the fund house literature, "BetaPro ETFs offer daily leveraged (up to 2x), inverse (-1x) and inverse leveraged (up to -2x) exposure across a variety of indices, sectors, asset classes and commodities." In the five days I owned it, Bitcoin lost 12%, and my investment fell 17%. Needless to say, I immediately sold, and ran back into my diversified equity ETF. Lessons: Never buy what you don’t THOROUGHLY understand, and always, ALWAYS do your research.
whqqq : yes. It's hard to expect to make money in areas you don't understand.
