Hi,
TKY TheKey got my attention - it is new to the market - available on Kucoin exchange from just a few days ago so price has settled down a little. It is ranked at a low position 1201 on coin market cap - so has immense capability to grow..
Moreover, unlike many coins -
TKY actually has a working product - already in use by social services in one Chinese province (independent news links below).
TKY solves the problem of authenticating your identity. The projects that succeed in this area are likely to have very wide adoption. There are other projects in this space - but TKY seems very far along - and seems to really use mining and use the coin in their solution. So, I think - not just a scam coin to pull in more funds.
I think I stored this on my Neon wallet - and therefore on my Ledger Nano - a big advantage.
