If you invest in FUN by buying it using bitcoin maybe the returns for bitcoin will also decrease because the price of bitcoin increases, but if you buy it with a stable currency maybe you only focus on losing its value, fiat currency is stable, I didn't lock it but I think there is it's good to just hold it in a freebitcoin account to get the benefits of WOF and others.

If you benefit from WOF maybe you can get other income to multiply your FUN token if you get free btc from WOF, usually I do like that if I get free btc from WOF I will buy FUN to double it, but talking about the value of BTC to FUN maybe it will continue to fall if the value of BTC continues to rise and FUN tokens remain stable or decrease, but let's see in a year or two I hope it will turn out to be profitable for you.
