Trading is more like gambling, he should stop it or only do it with small amount of money which he can afford to lose just like small amount of money that he can use to gamble and lose.
I want to correct this misconception. I have made a topic on this at some point, and I have also done my due diligence (DYOR).
Trading is not Gambling.
Yes there are similar risk factors: The potential of burning through all your capital. Yes they can both be unpredictable, but one is more heavily dependent on luck than the other: we all know which one, right?
Someone can trade as though they're gambling though, but that doesn't make trading gambling. This concept is personal and not general. Generally, trading requires deep understanding of the asset you're trading on, proper risk and money management, understanding of the law of demand and supply, etc. So please, correct this misconception.

This has come to my understanding how people are tracking the price of alt coins of their interest with the value and speculations of bitcoin. He also complained how he had lost about $9,000 at the course of the bitcoin market.
Almost all alts, if not all alts(haven't done a proper research though, just speaking from observation) are pegged to Bitcoin. Their price movements are relative to Bitcoin, not because as there are dumps and buys in Bitcoin so there are in these alts. No, but because their liquidity is often in Bitcoin. That's why we often observe this.
