You don’t need much to trade because the fees are a percentage of your trading amount. It’s not a flat fee. You can start with maybe as little as 0.1 Bitcoins or possibly even less than that. Of course the saying “you have to have money to make money” is true because if you principle is low, the profits are low too, but you have to start somewhere.
i agree with you starting investment in day trading as low as 0.1 bitcoins are enough as a beginners in trading, being a beginner didnot need to earn big interest as traders my reason trading they are have risk is hurt to as newbie trades lost a lot of money.
