No. STEEM will not double in the next year. Ethereum might, just because it went down as much as it did and might enjoy surprises.
Bitcoin and Litecoin probably have the best fundamentals being deflationary currencies, but I feel like while they may have some upside remaining in the near future and of course in the next few years, having an immutable blockchain that keeps growing, and being virtually not fungible (in Bitcoin's case, due to its higher fees) in real value terms, are bad fundamentals that unless changed, are going to hurt some Bitcoin holders.
Litecoin is less safe than Bitcoin, so I read, but is more fungible (lower fees) for everyday transactions.

Ethereum IDK if inflationary or not, I want to know.
Regarding STEEM, there were quite a few users here warning about the misdeeds and flaws of Steemit and its developers and management, and see how they are mostly ignored, and this is why Steemit's problems are going to be felt more, and STEEM will decline more, with a few spikes due to the crypto bubble and a few suckers being suckered in.
In principle, forks and ICOs are bearish for cryptos, except from their added publicity/hype factor.
