I would try to keep a balance of bitcoin and bitcoin cash - in that way if one of them are to be declared the "winner" you would have an equal position of each of them. It is indeed possible that there could be a flippenning - whether that happens remains to be seen it will take time. Keep in mind that the amount of people in the world in the cryptospace is around 1%...that's quite small...so in many ways there's a lot of maturity and development to happen in this space over the next number of years.
Eos pops to mind with regards to your question about other ico's on my radar. It will be in ico distribution till late june, 2018. (it's doing a one of a kind distribution model for it's ICO). I think Eos has massive potential.
Steem On, and Best Regards
Omisego and Neo are good long term picks in my opinion
Consider skipping christmas this year and investing the money! Dare to play differently - xmas is mostly a consumer holiday anyway. (just throwing the idea out there...i mean no offense if your super religious about xmas or something.)
litecoin, ethereum and dash - i rekon will all do quite well
