is it possible to trading without capital?
Without capital here means without money that come out from your pocket as capital.
If possible, i want to learn from very small thing in trading, yes without money on my pocket or my bank account.
Yes, it's possible, but it requires laborious tasks and effort. Invest some time and effort doing bounties. Through it, you'll get some tokens which you can sell, so that you'll have a small capital to roll in the market. You can also take a chance on getting "free" capital with some projects that rain "free" tokens called airdrops. Some are really profitable.
