Yes that is right, instead of margin trading we should give preference to do trading without our actual amount, which no doubt reduce the risk of losing all our money in no time. In fact there is a always a chance of making big money even by investing a small amount of your money, but on other side there is a risk of huge amount of money.
What do you mean by trading without our actual funds?
You mean using bonuses of brokers?
I hope you realize it is a tricky thing
Maybe "actual amount" means "the real funds you have"
for example, You have $10(actual) then you transfer funds to the margin account (i.e: 10 leverage)
so the funds to be available in margin trading are $ 100. actually, you only have $10 but you can trade equivalent to $ 100
if you make profits 20% from $100 you will get $20+$10 after repay (exclude interest)
