Sorry but I don't believe you dude, according to data from coinmarketcap and coingecko which are the two major cryptocurrency price aggregation platforms, Fun token has never reached a price of $0.4/$0.5/$0.6 as you have mentioned.
Right and I just want to add that the ATH of $0.3378 which has been reported by coinmarketcap was in 2017 when the FUN tokens was not avaialble at freebitco yet.
FUN token became available for buying at freebitco on February 01, 2021 and the highest price it reached after that date was $0.0687.
