Yeh most are useless I'd agree, at least 1,500+ I'd imagine. Others, that look really good in the top 20 / 50 may die out over time though. Look at the historical rankings of coins from the peak of the bull market in 2013, most of them that were at the top aren't even in the top 100 of 200 anymore... But interestingly enough, even though many will never re-reach new highs against BTC, they may in the long-term actually hold their USD value ironically.
