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
