But not that many of them will be highly appreciated by everyone and they're likely to fail than to succeed.
Altcoins are a different beast altogether. There are a lot of good ones on the market, although I haven't heard of any new and good ones in quite a while. It's probable that the best altcoins have already been created, though I wouldn't bet the ranch on that statement. Which ones are going to survive? Most of them I'd say. But that doesn't mean that most of them are going to be worth much, just that they're going to exist. Should prove to be an interesting year.
