I recently replaced my leaking condensate pipe that was crusty and rusted. I've replaced it with a 1" copper pipe in the same position the old galvanized pipe was. Please see the picture I've attached.
My question and concern that I have is that, the previous pipe that was on the floor of the basement was extrememly rusted. Much more than the vertical standing pipes made from the same material. Since I put the pipe in the same place, near the ground of the basement, would the pipe corrode faster from being so close to the basement floor?

Yes, the floor was the downfall of the old pipe, the copper will do much better. While everything looks dry, the floor & bottom of the wall concrete is moist from microscopic condensation, since they're always colder than the air.
Starting the condensate pipe as high as possible will minimize pipe problems & more importantly draining problems. You want the pipe pitched downward for as far as possible to the sump.
Preferably the pipe should never be flat or level & it should have a close by trap, like under your sink. The pipe should also have a clean-out, this is actually a bleach pour-in. Condensate is quite nasty & stinks if the pipe's not bleached once a year or as needed.
