Advice to new players, all corps seem to want PVP players. You can play the game without being in a corp, but if you want to be in one you will need to be up for PVP.
The game is more heavily structured to PVP, if you mine you will find there are no buyers for the low level stuff. Check the market before you invest in location charges and mining charges. The NPC charges 10x more for what it sells to you compared to what it will pay to buy the same item from you. I think you can make a profit at it, but it's not a lot. As an example from the market players are paying 30 per for items the NPC will pay 0.1 per.
Same for harvesting the NPC pays almost nothing for items, so if there is no player demand on the market there is very little if anything in profit.
The only real money making is doing the assignments, it's a mixed bag some end up risky or tedious others don't but they pay very well compared to the other options.
You can mine and harvest to build stockplies in anticipation of future player demand, that can work, but you will have to pay for the 'ammo' you need to do so. You will run out of money fairly quickly so you will need to do some assignments to keep going.
