I agree with you, the best bet is now on altcoins. If you like to take risk, then maybe riding the BTC wave until near fork then jump back to alts is also a good move.
I would like to add another "underdog" to this fight: BCH. As the 2 main chains: Legacy BTC and BC2X are fighting, they might lose their hashing power to BCH as BCH is updating their EDA on Nov13 --> We might witness an overthrown too (which is unlikely but it might!) --> keep some BCH in your pocket is also not bad :).
I have written a short analysis here: https://steemit.com/bitcoin/@bluephoenix/bch-vs-btc-vs-bc2x-for-investors
Alr upvoted. Keep up the good work!
