Bitcoin price is the only one that we can be sure of to go up. Since Bitcoin has more developers than all of the other crypto projects combined. The only relevant innovation is coming and will be coming from there. And the price will definitely reflect it.
As for other projects you have to keep in mind that it is the companies issuing their own currencies! And we all have seen how the companies make their decisions. It can't really work better than fiat. Best you can hope for is that the coin that you are invested in, is going to pump.
