I used to mine litecoin in the early days and was originally 80% BTC 20% litecoin, but sold all of it for BTC.
Now I have 99.9% BTC and .1% namecoin (for domain and testing purposes)
As far as investing, I would suggest people stick with BTC for the time being but balance their investments
with non crypto such as land, businesses(possibly crypto related), gold, and stable forms of fiat.
Any other questions, sir?
As to dying a slow death, the price in relation to BTC doesn't support this claim.
Unless it's implied all coins are dying a slow death.
Bitcoin is capitulating as well, Nxt at an accelerated rate(dropping from 3rd in market cap to 8 or 9th:

Keep in mind the price line is in relation to BTC.
Discounting newly pumped ICOs, not all coins are capitulating. Much to my chagrin, Ripple is growing in value.
I don't believe you Would you like some suggestions of other old threads to dig up for tomorrow?
That is why I have been advocating for a TaPoS security layer added to bitcoin over many threads and creating new
threads questioning 100% PoW in Bitcoin like this: https://bitcointalksearch.org/topic/changes-to-the-alogrithm-prohibited-or-disputed-873646
