The problem with trading and investing is that you need to have money to make money. Real traders put only 3-5% to one trade. Nobody can win 100% of trades.
Of course everyone needs money to start trading unless someone is satisfied starting at small amount from bounties and campaigns. Although starting small is always the best way to start as you will value every penny you have and become more wiser. Recently I started participating in ICOs so I can gain bonuses.
If you are new to trading then its good to start with a small capital and gain knowledge and experience first as even if you go through loss at initial stage it won't much affect your financial status and after gaining good knowledge and learning the tricks you can go with higher capital.
