I've been having a similar feeling about the alt-coins, just having a tough time deciding which I think are the best bet for a spike. I recently bought a couple of ETH just so I don't get completely left behind if/when it has an exponential climb. I'm working on diversifying my coin portfolio so that it's sort of like a Crypto-Index-Fund. Sounds good enough for me, I hope your predictions are right; but what makes you think XMR and LSK will remain it's relevancy (or even increase) after the future Bitcoin Forks?

I think after a few forks, heavy investment from trading futures and some developmental growing pains there will only be a few, if any, alt-coins that remain relevant.... I see an alt-coin purge coming within the next couple years, and only those that bring something unique and significant will thrive.

I feel like there are too many alt-coins, and too many of them are "cult" followings like an indie movie; a good chunk of them have a "hipster" feel to them.
