Yes, If fund is small amount in trading, lose also will be low, beginners should start trading or gambling with small capital, it's less risk. Also expert traders also use affordable amount in trading. Mostly beginners bought wrong coins with big amount of fund even at high price. Trading and gambling risk is almost same but both of different.
Professional traders may use more amount of money to trade. Let me let you know what professional traders are. Professional traders are not traders that only have in-depth knowledge about indicators, analyses or whatsoever. Professional traders are traders that trade and make money from trading. They can be 95% or more accurate in winning. So that will let them increase the money they use to trade. But as for beginners and those that are still losing more than win or those that are still using trading to gamble, they should use small amount of money that they can afford to lose to trade.
The amount of fast pace trading that professionals do is insane, I have seen some that does as much as 500 million dollars in volume, for a single day. That doesn't mean they have 500 million dollars to trade, you could trade 100 million dollars five times and that's 500 million, or you could do a million dollars five hundred times and that's still five hundred million dollars.
All in all, when someone does that much volume in trading, it's certainly not an easy way to make money and they are putting so much risk in it, when they are doing something this risky, it would not be possible for them to be novice, they have to be the best at what they are doing, in order to get a job like that and be funded that much.
