I didn't think it could drop this much... and these days I'm wondering if it will drop to 1 sat? Is that even possible?

13 sats which is its current price is the lowest it has ever been. For the benefits you get as a premium member that is an attractive price for acquiring tokens. Due to the exchange spread, however, users might not be willing to invest in the token. Converting from BTC to FUN and then back to BTC will cost you around 15% of your BTC at current prices. The lower the price goes the more value you lose when exchanging directly on freebitco.in.
Yes you're right, because usually they sell FUN tokens 1 sat above the price. So the more the price is low, the more the margin is relatively high. Currently you can buy them at 14sats which is 7.7% above 13 sats, while it's only 2% when the price is 50sats. So people are maybe less interested to buy them because of that.
Some of us made our first purchase at +60 sats... and where are we now?
I would like to stay in FUN investment, but my experience is pretty messed up at the moment...
