I have almost the same amount in cryptos right now
I would hold most of it in BTC lets say 50%
The 10% i would gave to really really promising icos i think 3 are good enough if only one skyrockets you have your money.
So you have 40% left. Give them to which are good, promising, have strong dev team,... and most importantly, they have clear and strong roadmap in Q1 2018 ...of course in whole year 2018.
I have most in NEO right now, ETH is always good choice. I think NEO is going to skyrocket, it recently went through difficoult audit so i believe that next year same date it is going to have the same value as the ETH has now.
Other alts I put trust into are
Stratis - the same reason as NEO
Omise GO
SiaCoin
Shift
I think POWR, syscoin and IOTA, MONERO...all of them are rally good choices but is up to you, but at least i recommand this percentage
