what are the advantages of trading in spot? I see there are many more coins available in spot but I guess that I should be careful with liquidity of those coins...
How can I know what coins to avoid? because of liquidity or manipulation etc? any tips when looking at the order book? spoofing etc?
When you are doing trade on the spot market, if within a certain time the price of the coin suddenly falls, it doesn't mean that you immediately lose your assets. It's just that the value has decreased. As long as you are still holding the coin, the amount will remain the same, if you continue holding and one day the coin rises again, then its value will follow the real rate on the market. So, don't panic easily when the value of your assets suddenly decreases when prices are dropping. Because, as long as the coins you take still have volume and are not delisted in the exchange, then your assets are still safe, you just have to wait for the coins to rise again.
However, this is quite tricky, because sometimes there are coins that when they go down, they will go down continuously and in the end they can no longer rise again. So over time, your assets will actually have little value and even if they are delisted from the exchange, it means your investment has failed.
For this reason, avoid various coins that are hyped, or in this case the coins that have skyrocketed hundreds or even thousands of percent on the exchange, because this will be quite risky if you buy them.
Choose only the top coins by diversifying, not going all in on 1 coin. I agree with some of the members here, use Coin Market Cap or CoinGecko to check top coins. The main thing remains in Bitcoin, so choose Bitcoin for a relatively large percentage of assets.
Oh yeah, apart from choosing which coins are recommended, you also have to make sure that the exchange you use is a top exchange, don't use new exchanges or small exchanges whose reputation is still questionable.
Regarding future trading, for beginners, it is not recommended. Because, if you have placed a position in the future market without doing research first, then the risk of actually losing your money will be really big. Because in future trading there is a leverage system, which will also have a negative impact on your future trading results if the market changes drastically from what you placed. And this means big losses for you.
