How is it that a trader would think that the reason he is blowing accounts is because he only has a small capital and so doesn't make it a priority to protect that capital, the reason being that it's an amount that he can afford to lose? Is it not weird that someone who cannot manage a small capital trading account would think that if he gets hold of an account with big capital, he can manage it very well and make profits consistently without blowing the account? Do you also think capital is your problems and reason why you are not profitable?
The whole idea of trading is to generate money and for most people, the whole idea is to generate enough to not work and in the best case, they want to generate as much money as possible. When you have $100 and 1-2% profit generates you only a dollar or two, that's definitely not enough for anything, you'll only be able to buy a water, soda, beer, bread or an ice-cream. But if you have $100 000, generating one or two percent profit means that you are generating $1000 and $2000. This money is enough to make you live very well in many countries and live standardly in developed countries. Now you understand why people with low capital easily risk. They do it because $2 profit doesn't count and they want more, at least a hundred dollar and a huge capital gives them this possibility, so it's not weird to assume that people who can't manage a small capital, will manage account with high capital very well.
