Don't be hard with yourself, whoever bought those coins had inside information.
Look at the graph, the uptrend began 1 month before the announcement itself.

I sold mine for 0.005 as well

As a former xcp holder, I used to follow XCP trading quite closely.

XCP was traded for 0.003 for months,
30-45 days before the announcement about the etherum protocol implementation on top of xcp someone with inside information begun to buy massive amounts of xcp's.
The price drove up slowly up to 0.017 at the day of the announcement itself.
The hype took it higher to the range of 0.022-0.023 and after few days of trading someone pulled like 80% of the buy orders resulting in a very thick buy book.

You can call me paranoid, but that is my opinion (just look at the graphs before you kill me for fudding)


edit: I am saying this because in my opinion we still have a way until *real* floor is reached.
I am keeping an eye as well although currently I have no free btc to invest anyway (xcp is a great project with a great team I am just not sure about its current price).

The floor should be a bit higher then 0.003 which was the price before the insider pump, anyway I won't touch xcp again because they are playing with inside information - honest investors have no chance in here.
