thank you everyone. I just transfered 0.5 BTC to Poloniex and ordered:
8000 STR
3000 XRP
3000 XEM
3000 NXT
10 FCT
On Kraken I have
500 XRP
5 ETH
2 XMR
& 1000 EUR
Bought in with 2150 EUR...do you think there is something to optimize, or do you see any wrong decision?
I'm not going to descend into the details of each coin but I really advise to read about them which I mentioned but you haven't consider yet.
Thanks for your advice. Of course I read about the different coins' technology, announcements, comments etc. - so I will stay informed. But it's hard to say for me, as a newcomer if it is a good point to invest now for 1+ year. Also the main problem is that I don't know if it matters (depending taxes) if I trade within altcoins or if it only matters when I transfer fiat <> bit/altcoins. If it's no problem trading within cryptocurrencies witchout breaking the '1 year' rule, then I would of course trade between the coins over the year. Otherwise I would hold the coins and do nothing.
