I have never done such detailed calculations on buying FUN. Er, I am usually just buying the FUN directly by sending bitcoins to the freebitcoin account and enjoying the premium benefits. The first reason is I am keeping my funds away from the centralized exchanges for now. I really had lot of trust on the Binance but in the recent events that is also getting worst with Binance. It's unfortunate and its entirely different matter. Anyways, I hardly think that can make any big different. Few dollars here and there won't benefit much in the long run. We can have that compensated with the premium features of FUN in no time.

Speaking of which, I would like to share I have now reached 1200 WOF collection. I am still holding them and wish to continue this until I break the record of 2K WOF. I have read on this thread itself someone rolled about 2K WOF, so I am willing to do that again and want to break that line too and see how my luck plays for me this time. Hoping for good amount of sats and RP's.
