I defined eight basic levels of cryptocurrencies. What you think about it?
Tokens Tiers.
Tier 1: Bitcoin & Ethereum
Tier 2: Tokens representing real crypto platforms (Cardano, IoTA, Waves, ...)
Tier 3: Tokens backed by real business (Ripple)
Tier 4: Tokens with narrow specialization like payments, anonymity, etc. (Monero, Zcash... )
Tier 5: Growtech forks (Neo, Stellar,...)
Tier 6: Miners' forks (Bitcoin cash,...)
Tier 7: Hyped Tokens
Tier 8: Useless shitcoins
So, I've tried to put first 30 coins on those tiers mentioned above.
BTC - 1
ETH - 1
XVG - 3
XRP - 6
LTC - 2
ADA - 6
BCH - 5
NEO - 6
ETC - 7
ICX - 2
IOT - 4
DASH - 2
QTUM - 5
XLM - 2
XEM - 2
LSK - 4
XMR - 2
WAVES - 6
BTG - 7
WAN - 7
SC - 7
ZEC - 2
EOS - 2
ELA - 2
HSR - 2
BTS - 2
Steem - 2
NANO - 7
BTM - 7
TRON - 7
Your classification is quite arbitrary. For example, why do you consider Dash different from Monero? If it is different, why not a fork? Remember it is a fork of Bytecoin.
