I start: NANO.
1) The most down from its all time high value after Bitcoin Diamond
2) A completely new technology that is already being re-use by many ICO
3) A working cryptocurrency that brings greatly needed features: very fast transactions, 0 fee, scalability including a ledger that can be pruned...
4) It has 0 inflation and at least 20% of the coins are frozen (Bitgrail wallet, developer funds, faucet tests)
