... They perform just like any other ETF's or stocks even though they are structured differently ...
Nope the 3x ETFs do not perform like every other ETF. Their value decays much more rapidly if the underlying index is very volatile. For example, if the underlying index goes down 5% one day, then increases 5% the next, $100 in the 1x ETF would be worth $100 x 0.95 x 1.05 = $99.75; the 3x ETF would be worth $100 x 0.85 x 1.15 = $97.75; i.e. much more than triple the loss.
