What is the minimum amount of BTC required to trade on Exchange sites?
Our goal is to earn dollars. At least how much BTC should start with trading on Exchange sites.
If you are a beginner,I suggest never start with more than 0.01 btc as trading is risky business.I have lost 0.025 btc and haven't learnt anything

When you learn the rope and know some basics of trading, you can invest more.
