for my understanding: if i put 1000usd in i can sell those the next day for 2000usd? (because of the staking)
not quite because the coin supply is so big now that you really can't solo stake in your core wallet...you need to join the staking pool and there is like 10 days left of the 10000% staking so you can still earn from it if you jump in now.
I posted info on how to join the pool at:
