Also now I have two more ways to do money
For example it's called in trading "beer" method
It's like as you know Bitcoin all time will grow
So today Bitcoin cost $3000 and you have $1000 to invest
In two days price coming down for a $2200 but as we know price will back to a $3000
So we buy BTC on $1000 for $2200
And sell BTC again to a fiat when it's will back for $3000
This way is good strategy to earn some additional cash
Because all time we knows what price will rise

Another way if you living close to Singapore you can buy there are for a cheap price new mining GPU and resell them on eBay or here on forum for miners for X2 or X3 price
I saw how cards which really cost just a $70 was sold on eBay for $350+shipping costs
