we should focus on just its movements like when the price increase we should buy and when it falls we should sell. It's all about knowing the perfect time to take steps about altcoins.
I believe the same things are applicable even when you're trading bitcoin against fiats. I mean these watching price movements and finding right time to react are common even for bitcoin trading.
We need to remember the competitions in crypto trading is not like the early stages of its market. After the introduction of derivative exchanges, the crypto trading volume has significantly increased which means if you're not alter enough then you will simply miss out your entry and exit so cheaply. On this regard, there are no big differences between trading altcoins and trading bitcoin.
There's indeed no big difference in trading bitcoin and altcoin but bitcoin trading is still the better option for especially the beginners cause its price usually maintains so balance while the altcoin market is highly manipulated. However, I think Best Dreams don't understand the aspect of how the market trend change simultaneously which make it hard for some traders to make a profit due to the huge competitions so trading is not all about focus on price movement and knowing the time to enter/exit because the knowledge of select the perfect coin need to be included.
