Since this is a bitcoin discussion forum, then most of your questions should be about bitcoin, discussions about other cryptocurrencies, that is altcoins are also welcomed, but you will have to post that in the altcoin section.

About trading, if you are asking about how to get started with trading, then i do not think you should trade at all, because you wouldn't know what you are doing, which will lead you to many losses.

If you are new to cryptocurrencies, it is advisable you forget about trading at the beginning, get a hang of other things, understand bitcoin, its network and the crypto network generally, then later on, with the understanding you must have gotten, you can now decide if you should trade or not, and if it will be profitable for you.
