Do you want to be a pope with big money can control the market? I think the pope has his own funds.
I don't know how you do it, but have you run out of capital? If you still have funds in your pocket then do it as a trade enough with your capital when you can get a profit then it can be collected for big trading funds.
Remember! Never take a loan for your ambition.
Trading for 4 years is not a short time, the OP should have learned how to collect the profits earned, so that it can be used as capital for trading.
So finally OP can have a large capital for trading. That's why we have to start trading from small capital, so that we can learn how to turn the profits
we make into trading capital. Because after all the profit that we make from trading, it will be the best capital for trading. So want to have big capital,
the best way is to collect the profits we get from trading, the process is quite long, but has a small risk. Don't expect to get big capital from loans,
because borrowed money if used as trading capital will make us experience financial problems in the future.
