I am happy for you @OP, in our country, that amount is really huge so I can understand the frustration and "hopelessness" when FTX goes bankrupt and your money is in it. Now that you recovered you fund, it is a wise decision that you convert it all in BTC, I would do the same because of the trust established by Bitcoin in its market.
At first I felt like calling you out @GreatArkansas, like why you? Because you are a legendary member of this forum with alot of experience but then again, my mind tells me that it could be anyone.
If you haven't known, FTX is too popular back then. No one ever thought that exchange would collapse, it is possible that @OP is trading something or converting some cryptocurrency and his funds were in there when the scandal happened. Just like anyone would not suspect Mt. Gox would get bankrupt, but it did. I also don't think it was a mistake trading or investing in FTX since all their documents (founders) seems credible they (founder and some staff) even donated funds to US political party.
