Explain Like I’m 5?: The Saylor Strategy

i was wondering if anyone could explain Saylor's strategy on what hes doing with his company in order to buy so much Bitcoin? Especially in this video here: https://youtu.be/KUHl7RmDW7I?si=cLVpEyBu3Bp5IRM_

He explains what he does, but he uses a lot of financial jargon that i dont understand (like "arbitrage: "derivatives" etc). i dont have a financial background, so i get lost in what hes saying. i think its cool he backed his company with BTC and that caused MicroStrategy's stock price to go up, but i want to understand the "why" and "how" this is happening.

Are there any risks in what hes doing? People on X and reddit are saying he found a "cheat code" in the system and that other companies should follow;. Peter Schiff on the other hand thinks hes gonna go bankrupt (which i think is extreme, but who am i to judge?). Is what Saylor doing ethical and safe? or is he building a house of cards that will collapse? like how is he able to issue so much money out at an almost 0% interest rate?

please if anyone can explain and simplify that would excellent !! Keep stacking sats ????????????
