This is how a 60000 euro portfolio will look like if you buy 10000 euro of each of these 6 cryptocurrencies. I think there are significant odds of seeing the rally extend until the end of 2017, when Bitcoin's long term uptrend signal expires. By then I would advise extreme caution, since it would become probable, although not definitive, to see BTC stall or even fall, for the next 2 years.
Best of luck,
