I don't know how anyone can tell if there is amateur trading but what I can tell is it is one of the most unstable trading etf's I have seen maybe because it is distinguished from an exchange-traded note since it represents an ownership claim on underlying securities that the fund has packaged. Seems after the reverse split it limited the high volatility by having a longer time frame in months and made it operate more like a mutual fund. The liability that may or may not occur is taken with more time( more months) compared to before is was a short one month term.
Well looky looky here is some evidence of amateur trading for ya. "Free trading app Robinhood has added more than three million accounts in 2020, and now has over 13 million. The median age of its customers is 31. The Covid-19 lockdowns and the plunge in markets in March persuaded millions of new investors to open accounts. Some of the action appears to be from people who would otherwise be gambling or betting on sports—both of which were shut down."
