Re: eight basic levels of cryptocurrencies.

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

Not only Ripple is backed by real business, and sometimes useless sh*tcoins are hyped too, but I agree with you in general. Indeed, Bitcoin and Ethereum are the most promising ones, and tokens like Cardano and IOTA, although they are falling right now like all others, will most likely be doing good in the future since they are representing unique and useful platforms. And, like you, I too think that miners' forks will hardly have a future in the long term, so, they are rightfully placed on the 6th tier.

How about tokens created by messengers, loyalty platforms, crypto echanges and other real working businesses? Should I put them in Tier 3 together with Ripple?

I think Binance Coin (BNB) and Huobi Token (HT) have the potential to increase in value over time because they will always be supported by the great exchanges they represent. I'm not sure about the others though. Speaking of Telegram's Gram, for example, which is probably the most promising token created by messengers, I wouldn't say they are safe to invest in right now. Firstly, the public sale was canceled and if you see a site selling GRAM they are most likely scammers. Secondly, I read that the unofficial sales, which are going on right now can complicate listing it on exchanges or setting a post-ICO price. In short, I would put Binance Coin (BNB) and Huobi Token (HT) in the Tier 3, but I'm not sure about the others.
