Hey there...
I think its a really good time to invest in Bitcoins and not only in Bitcoins.
I bought Bitcoins for 500$ as they were at ~400$ in early November or late October. I hoped, but didnt really believed, that they would go above 600$.
Finnaly i selled them at a price of ~900$. Did the same again.... and again... switched the crypto-currencie and did it again with PTS... again and again ...
Started at the end of october with 500$ and got until now something between 1800 and 2500$(Didnt know exactly) just with exchanging it many times =)
Btw: I started to mine new coins with few dedicated servers ... Started with PTS few days after the beginning .... got me ~450$ after exchanging to BTC and selling the BTC
Now I´m mining Memorycoin 2.0 ... mining just with 4 dedicated servers... found 5 Blocks so far.
Yesterday I started to mine Dogecoin with my GPU at ypool.net .... got me ~60.000 Coins... lets see what this will bring. =)
Greetz,
