I've been trading alot recently, sort of like gambling but with less risk to lose everything in one swoop
trading need more capital to get big profit..if just small we get a less..maybe you can try trading in altcoin its quites big profit in there.
gambling not recomended,will be lose just in single bet. it depend also.. if predict good then will be win..
You can always try trading with leverage. Which means when you have $20 then you can, with leverage 10 times, trade like if you have $200. You can profit faster but lose faster too then.
If you want to try then okcoin.com is the best place because they have high volume.
