Isn't NEO targetting mainly Asian people

Horizen is over 1 year old and is for sure a profitable coin, without considering the fact you can earn more if you operate a super node or a secure node.
So yeah, some old coins are still profitable

Because the bounty hunters and the early buyer sell as soon the coin is listed somewhere. Since there an important volume of sales then the price goes down

And ladies and gentlemen.....
7 Reasons Why This Is the World’s Most Exciting Blockchain Project Right Now

https://cryptolawinsider.com/horizen/

The community is (generally speaking) happy to see such services launched as it shows the growing interest and it helps the ecosystem.
I have neer hear about a scam service so far,  however there are some with a good background, if you check the discord channel you may find some discussion about it.

Horizen belong to the sleeping giant, and yep, the coin is going to wake up very soon. Start to buy your coins and #HODL !
Run a secure node or super node to earn more and let's go to the moon together 

So many bitcoin forks
But I didn't know Bitcore and started to read the white paper. Going to finish to read it home but It looks more interesting compared to all others forks


Bitcore implements true decentralization and user empowerment:
- Bitcore‘s ASIC-resistant mining algorithm restores community participation and counters
centralization effects in mining.
- Bitcore’s application of Bloom filtersi
significantly reduces the required storage to run a full
blockchain node, enabling more individual users to become fully empowered Bitcore
participants via SPV/light wallets.
- Bitcore’s novel airdrop process resulted in a decidedly more equal distribution of the coins,
encouraging Bitcore’s use as a means of payment. The Bitcore community‘s decision to forgo an
Initial Coin Offering (ICO) has kept speculators at bay.
- Bitcore is faster than Bitcoin, faster than even Paypal, enabling it to become a real everyday
payment option, thanks to its timely implementation of SegWit and other design decisions. On
the Lightning Network, a theoretically unlimited number of offline transactions are supported.
Bitcore’s low fees of around $0.003 USD per transaction make it even more suitable for
everyday use and render micropayments feasible.
- Bitcore is an open source project: Collaboratively produced, shared freely, published
transparently, and developed to be a community good rather than the property or business of a
single company or personii

To the OP

Altcoin = alternative coins

So, as the folks above are saying every coin (beside Bitcoin) is an altcoin, because it is an alternatice coin to Bitcoin
It's just a words combination shrinked

Monero is only good for a very short-term investment. If you are really interested in privacy coins and for a higher ROI, in the long run, you should check Horizen project, it's good since last year

Why are you looking for prestige to use a crypto exchange !?!

By the way there are thousand and it's not difficult to find one. go to coinmarketcap you will plenty of them

Beside the spams you are facing, how active is the group?

Spectrocoin is, if I am correct, not using anymore Wave Crest as issuer since some time.

edit:
So create an account and verify if you can so something

It's a very old scam and not so new for people involved in cryptocurrency. The sad part is people who fail in the trap, not sure who is to blame here, the scammer or the people scammed. There is an interview online about this scammer, he claimed to make $50,000 daily and hired a dozen of guys to work for him

Some coins aren't in the Top 10 but they do worth more than some in the top. Horizen currently is undervalued despite the fact its tech is more interesting and promising than few in the top 10

There is no need to reserve a "slot"
 Horizen is based on its community and participating on Horizen is based on voluntary work. Everyone is able to help the project with whatever is his skills. Many people participate to the Horizen platform free of charge just because they support the project

Probably a privacy coin and I wouldn't be surprised if Horizen is finally being recognized at a interesting and promising coin

And how do you want central bank stopping us to use Bitcoin? Who are they to give use us directives?

Amazing to see a cryptocurrency participating in charity 👍

You found the reason. It's the first one and not the last. That's a problem when you a company. The ToS can change at any time and usually without any warning. At least, I hope you didn't lose a lot
Sometimes companies don't give you a clear explanation in such a situation because they don't want the change becomes viral on the www

You shouldn't give any financial advice if you are not a financial advisor, banker, funds manager or whatever. No matter if the market is doing very well or very bad. If your family or friends lost a lot of money what are you going to tell them then? Oh sorry my bad, I will refund your loss...
Nope...
