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.
In as much as I believe almost 90% of altcoins are not worthy of investing I do not believe that TRX and XLM should be in that category. Your only reason for adding them in that category is because of their giveaway or airdrop, which I don't see anything wrong with it, what of those which aren't doing Airdrop whhy aren't they performing well? The issue here isn't the airdrop but the team and if they are still working hard like before or if they are tired; and this is why most projects are lagging behind while most are performing well.
