in my opinion a computer or laptop is the same for trading, but what must be considered is that the laptop or computer system may be from the specifications of the laptop or computer we use, maybe that's it, for me the specifications that I use are mandatory.
Yes you are right we can use both but I think it is all our own choice, I personally dont like using PC and I prefer using laptop because it is easy to carry and we can easily trade with it, we will not have to stay bounded at one place but we can take our laptop wherever we want to go, so I found it easy so I use only laptop but many people use PC.
