Thoughts on Yieldmax long-term?

As far as I know, Yieldmax has been around for about two years now after starting with their initial fund TSLY.

I’ve got $2k in YMAG, and have been DRIP’ing for about 6 months. I have another $10k in QDTE which I’ve also been DRIP’ing since inception, almost a year now.

I’ve heard many opinions that claim Yieldmax funds are a great accelerator for a portfolio, something to hold for a good year or three and then transfer into more reliable investments;

However, as time goes on and I see the development of companies like Roundhill and Yieldmax, I wonder what their long-term viability is? They haven’t exactly established themselves only being on the market for only two years of what has been a great bull run, but I’d say the funds have generally performed exceptionally enough to make their mark as well-performing assets.

I think the true test of these companies and their funds is how they will handle a bear market for an extended period of time. I feel as if that should they be able to contend with the ETFS of other major financial institutions, and the NAV can remain relatively stable, these funds have a good chance of sticking around.

My biggest worry is Roundhill and Yieldmax go bankrupt somehow and I lose all my money lol. But surely with the expense ratios they have and the options revenue they’re able to generate, longevity would be a given?

What are your thoughts? Is it stupid to consider these funds as viable long-term? Or do you think that these companies and their funds are here to stay for the long haul?
