I also missed the moon accumulation at 1sat. I sat there staring at it like "this coins a joke" while it was fixing to take off. I was going to buy at 2sats and was like "nahh I don't wanna give the 1sat buyers 100% profit, maybe holding the bag. Missed my chance". Ultimately, I kept doing that until Cryptsy added it and missed out on a ton of gains.

Now Moon is back down to 1sat after falling from the 30s. Cryptsy is removing the BTC/Moon pair.

Buying at 1satoshi has little risk since you can sell for what you bought but when there's no buy support, it might be hard to sell at 1satoshi and a lack of volume could ultimately mean the exchange removes the coin.
I bought Corgicoin at one satoshi, sold all I could at 2satoshis and now look at it. Dead. https://poloniex.com/exchange/btc_corg
So, it is very possible for you to buy your flaps at 1sat and the coin gets removed from the exchange, making it dang hard to sell even at 1sat.

Ultimately, if the whales want to pump this coin, Mooncoin proves they have the power to do so. Even at 2satoshis though, this coin is still being hit pretty hard by multipools.
I have buys at 1sat, totally worth the risk.
