Coins I deem undervalued with long term value, offering something to add to bitcoin.

Any views, esp objections, welcome.

QRL:

Strengths: Long term approach to securing crypto currency against the all powerful quantum computers that pose a substantial and potentially immediate threat to bitcoin. 

Peercoin:

Strengths: A strong community of developers with well thought out ideas looking at long-term development of dentralised power - good at countering the centralisation of mining and power which bitcoin struggles with.

ETC:

Strengths: A proven resilliant coin when bitcoin and the market dip, often ETC will stay positive, this is due to its popularity and commitment by developers.
