By the way, if we gather fun tokens on freebitco, do we also get interest on them as well? and if so, the same percentage 4.08%?
I have not tried the FUN token investment. But I do participate in the Bitcoin investment which gives us 4.08% per year. I have seen the section dedicated to the FUN tokens and it is in my view another investment scheme running on the site which uses the FUN tokens that can be bought using BTC on the site itself with reference to the exchange price widget in the same page. That FUN token interest is separate from the bitcoin "savings account" interest.
Correct me if I am wrong though. I have not used or touched the FUN tokens section much.
