I recognise your thinking :-)
For the most part I HODL and after some crazy weeks I put a lot of profits from the Play Money into the Core coins. I also did some profit taking though. In the coming days I will probably write something about that.
Good luck with the flavour of the month coins! Any coin in particular that caught your eye for January?
Not for January, but I did find one for February that is very very promising, go check it out!!
It may be the first ICO ever that I will invest in!
edit: may invest more than 'flavor of the month' amounts too
