I used a large amount as capital for trading and at this moment the only amount being left to trade with is $200 I lost all my funds to spot trading.
Your comment here is ambiguous. It's not clear where you didn't mention how much was invested but you told us how much was left. What percentage of the capital did you suffer as loss so we know what we are dealing with here. Trading is about loss and profit. We don't expect it to always end in profit. Loss is a part of trading.
The worst part is that we do not know what he bought and suddenly lost that much money. For me 200 bucks is not a bad place to start, you will not suddenly become rich and it depends on your nation. However, if I can save 200 bucks per month then I would be considered a rich person in my nation. It doesn't happen at all because not many people make enough money to live and then end up putting money aside as well and hope that it gets better, because most people in my nation lives with 300 bucks salary and that is the biggest problem.
What I believe he did was that he lost a bit of money when his trades went wrong and he sold them instead of waiting. If you just sell when you should be holding then you are going to lose a lot of money. If he showed his trades then we would basically be able to see what he did wrong and can tell him what he shouldn't do.
maybe, at this point he already learned his first lessons in trading. it is hard to know what happened as we don't know what coins he traded with that he lost a lot of his money. usually, people lost in this trading when they bought the coin at its peak, and then sold when the coin is going downhill (owed to panic, fud, etc). and this will surely happen if unluckily, he bought a pumpndump coin or scam coins.
if you are a beginner, stick to top coins like btc or eth. start using small funds also as you are just gaining your knowledge in this area. you can't learn all the crypto trading tips & tricks overnight, it would take time even to spot pnd coins, or crappy ones.
