1. I can buy a decent used GPU for 600 usd. It will help me in my work, give me a good advantage in a rising competition. But I can continue without it. it will boost my art. Also I'm into AI research and it will come in hand.

And full pc will cost around 1200 usd. I can sell it with a 10% profit.

2. I can spend this money on goods I sell. 30% and more profit in 1-2 months.

3. I can spend this money to make a little repairs on my cars. Nothing critical but it will be good. also it's easier to sell car if everything is ok.

4. I can spend this money on new working equipment, but I don't know yet if I really need more of it. also it may not be available later. it's very hard to resell

5. I can upgrade my mining hardware. it will give 120 usd more profit each month than I have now. and I won't sell profit until next bullrun. but it's hard to sell and buy equipment in a short time - I need a buyer and wait until new hardware ships.

6. I can just keep money. but an inflation can take 10-20% of savings in a short time.

Also I may immigrate in 3-4 months. Situation in the world and my in life is unstable. I got 12000 of debt and 12000 of savings.
