These are my investments and how much I put in them. Looking to HODL until December 2018 or Jan/Feb 2019.
BTC ($500) << $2000
ETH ($500) << $2000
LTC ($500) << $2000
NEO ($500) << $3000
VEN ($500) << $1500
ICX ($500) << $2000
EOS ($500) << $1500
NEB ($500) << $5000
ENG ($500) << $2000
SUB ($200) << $800
WABI ($200) << $600
POE ($200) << $400
LEND ($200) << $200
DRGN ($200) << $800
UTRUST ($200) << $800
THOUGHTS???

That's my rough break down of those coins, some could go the other way, some could do better.
If I'm right all up that's $24,600 and a lot will come down to BTC price, I can't see ETH and LTC doing 4x sat value this year.
$50,000 is possible but will require a very good year, you've got quite a few high cap coins which have recently been pumped.
I would love to say we will do as good as 2017, but as of right now I don't think we will.
