What is the better way to get around 5k USD value XMR: buy it at current price (190k) or mine it?
Mine it if you have access to a boatload of free electricity and hardware.
Otherwise buy it.
I have free electricity but no free hardware
then yeah, buy it. Otherwise you're looking at buying thousands of dollars worth of 290X's in order to get 5k XMR in any reasonable amount of time.
But what if I buy the mining equipment for several k of USD, mine and sell 5k USD value XMR and then:
1. Continue mining XMR or other coin or
2. Sell the mining hardware with 20-30% discount of the original price
Don't get me wrong, I'm strong advocate of increasing the network hashrate. It just depends on what kind of time frame you want to work in.
If you have a time frame of a year, then 15 kh/s will get you 5k XMR (roughly, and this assumes no change in difficulty, and doesn't take into account the decreasing block reward)
15 kh is about 18 R290X AMD cards, which is the highest hashrate card right now, which goes for about 350$. , so thats a GPU cost of $6562 , and that doesn't even include power supplies for these beasts. So it'd probably be around , i dunno, 8k USD.
IF your time frame is less, than the numbers move around.
