This is the same shit that happened in the blocksize wars, really stupid people not understanding development and technical issues. It led to those people fucking themselves so be wary. Also in the blocksize wars and now - floods of misinformation and fear mongering from core proponents. USAFs are the devil, you will be forked off, your Bitcoin will be vulnerable etc. Bitcoin culture gets corrupted. Retards like this making videos about topics they passionately misunderstand.
Its just the classic buy borrow die financial strat repackaged for Bitcoiner holders. The idea is that you hold onto the appreciating asset, borrow against it and pay back the inflating currency - maintaining your exposure to the appreciation of BTC. There are potentially some tax advantages to this also, since in many jurisdictions Bitcoin is considered a capital gains asset (Taxable when sold).
Bitcoin is already spam resistant. The issue lately with core and inscriptions is telling node runners what policy will be. My basic understanding is that bitcoin runs in cycles. And historically it outperformed every asset class like the S&P 500 and even real estate. If you're someone who has a few hundred bitcoin trying to manage taxes pledging 5% of your stack as collateral, sure. if you're new to bitcoin, just ignore bitcoin loans altogether and thank me later.
And there are two main ways to look at it:
1) Using 0% corpo bonds to start a speculative attack against the dollar like happend similar to the most well-known speculative attack was against the pound occurred on September 16, 1992, known as Black Wednesday.
or
2) Using unwitting investors funds to multiply his corporate leverage, taking advantage of investors that either cant get corpo debt or buy bitcoin directly, leaving them with third party risk, a majority of the downside risk, for a small share of profits while he keeps the rest.
