A lot of alts look low relative to BTC at the moment. I think when the recovery starts properly, good alts will recover by a higher percentage than BTC, given that alts have fallen further.

ADA might be a good choice as some of the hype has died away now, but if the $1000 is your total to spend then spread it across a few projects - if you like these three, then go for all of them - but DYOR on them all first, obviously - make sure it's a good project before you buy in.
