A lot of discussions on forum are all about "what coin should I buy? Why?"
Here's the opposite - I want to ask what alts you would never buy and why so.
My example:
Never buy BTT, Tron, Stellar and other coins where the tokens are giving away with all kinds of airdrops. Why? Emission grows with no influx of investors.
Doubting about Peercoin. Hybrid emission system doesn't seem reliable too, though lately PPC began spreading itself via well-known exchanges (changheangel or changelly - don't remember).
+ Libra. Not sure if any explanation needed.
According to those you mentioned alts I don't bet on them especially the stellar I have not found a project to use their platform which is as good as its price on its stellar platform, instead, I prefer Xem , Eos, Kcs, Tky, and Dgb and others. So be careful about buying coins so that we are not happy to invest as a trader in the crypto business.
