You can start with a minimum deposit of 20-30 dollars.

Do not enter a trade with a margin greater than 2-3% of the deposit and leverage higher than 5.

The most important thing is to endure the moment when it seems that you are earning mere pennies, because think about it, 30% of the deposit per month, which is only 1% per day, will bring you x16 in a year, and x250 in two years.
