Thanks everyone for their help,
I was able to get ~200k coins on coinexchange and successfully put them on my PC wallet.
If I understand it correctly, the amount is much too small for regular staking, but I may get a small amount a few times per month, correct?
My last question is, do I just leave them on the wallet on my always-on PC and select "unlock wallet - staking only"? This is all I have to do?
(Sorry, my first POS coin). Thanks again!
(the status is "you are staking dust" - this means too small amount of coins to stake?)
