There's a lot of them but I got reminded of this coin in particular: Minereum (
https://coinmarketcap.com/currencies/minereum/) I think it's pretty much dead in the water. A project with an unknown team with almost zero social media presence. ATH close to $8 and now at $0.004 per CMC.
When you say there are a lot of them, I'd like to point out that Yobit currently has TONS of altcoins listed, and most of them are completely dead. If you own any of them and put in a sell order, you'll never get it filled. For a while, they were giving away some of the worst of the worst, and I currenly own PWR, TOKEN, EPC, STRB, and ASAFE. If you asked me what those coins are, I couldn't tell you--but I can't sell any of them because there aren't any buy orders in sight.
Just because a coin has been beaten into the ground does not mean it's a good buy. Do a little research into a coin's community and liquidity. Right now there are hundreds of altcoins around, and I would venture to guess that only 15% of them have any future whatsoever. Probably less than that, but I'm in a good mood right now.
the price of altcoins start climbing in USD terms but not in bitcoin terms,
That doesn't bother me in the least. As long as an altcoin is increasing in terms of fiat, I'm cool with that. If it goes up in terms of bitcoin, all the better.
