Everyone's brain experience is the same or different. But i can say that bitcoin is best for investment or long term holding but above all profit depends on how much dip opportunity you can buy bitcoin. Moreover bitcoin will give you a lot of security and your money will be safe because there will be no issue of scam here. So if the crypto market is in your favor it is possible to get dip price from bitcoin so you should be alert. However with crypto you can't go out of risk so you have to experience and deal with risk.

On the other hand i think trading is not good for newbies and especially diving into trading from bitcoin is more risky. So you can practice trading from other coins if you want and start trading later when it is available to you. But certain pairs need to be supported and equipped with fundamental analysis of such exchanges. Remember you need to extra time and risk is required to trade. Anyway you have to spend a lot of time looking for signals.
