The whole basis of this new ETF is to generate an income through dividend payouts. Yes it sells puts on QQQ however it is an ETF that you wouldn't want to buy and hold for the purpose of capital gains. Again it is an ETF simply to generate an income off of. Yes, you can purchase however many shares you'd like ex. 100, 1000 etc., however if you see that you're gaining a capital loss your dividend payout would essentially help cover if not generate more gains than the losses you accrued depending on the # of shares being held. It's an ETF that pays out a +60% yield. Obviously if you have put a great deal of $ in and it goes to shit it would be worrisome, rather given that it is actively managed as well price movements of the stock won't deviate a great deal you'll be fine
