Not to discourage you but you wont be able to make a living outta of trading with 250 and it’s a wipe out.
You might wanna try flipping 2nd-hand items online instead. It made me at least 2.5k per month doing it.
All you need is a camera phone.
Purchase almost perfect condition goods at least 70% off the retail price. It’s to save the hassle of having to clean up the item.
Clean it up if necessary to ensure it’s ready for a nice photo shoot.
Re-post and describe it as almost new conditions at 10% off the retail price. Drop the price by 5% every 1 or 2 weeks until 50% off the retail price.
Just wait for buyers.
Not to be rude but consumers are native, which is why companies make money selling their 1 dollar manufactured costed goods at extreme high retail price.
Hope this help. =D
