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.
Ripple once was distributed via airdrop. Look at this coin now - top3 of the whole market and lots of perspectices in future.
but how much they was gived per person,I guess not so much and the price will not crashed after airdrop
