Well ether is already pretty close to that price right now, and had crossed 1k a few months back, and with any decent uptrend in the crypto markets ether will cross 1k pretty easily. That being said that's not really a pretty difficult prediction to make. with regards to ltc and monero now its a lot harder to make that prediction, honestly both are good coins and ltc has a pretty large community especially after its last run up in December.
However from a fundamental point of view i personally don't feel that ltc offers anything different to btc, and with btc fees currently being so low it really dosen't seem to have any real use case or at least a very narrow use case.
Monero on the otherhand i feel is really undervalued right now, it never really rocket up as much as the other coins in December, and from a fundamental point of view is truly brilliant, Its privacy features have massive utility, especially considering how many governments are now actively and forensically monitoring the btc blockchain, resulting in a massive loss of anonymity. Consider how much money is moved around throughout the world using
