Win-win situation, I love it! I tried to do the same with a little part of my holdings (about 5%) yesterday, which is totally stuck in Binance for now. Sold at $7400 and thought the same thing, "if bitcoin goes down, I'll buy back from this USDC bag, if it doesn't go down, I still win with my remaining holdings". But then I bought back the BTC (FOMO'ed at the dump) at $6800 as I liked the little 0.03 BTC profit off that Binance bag.
Based on what you've just posted, your holdings must be around
6.8 BTC. Not a small amount, well done!
Keep HoDLing!
