As a newbie those tools you listed above not the major things that you can use to start your journey in this forum, this forum is all about having a enough knowledge that you can use to discuss with other people here they say that leaning is a continue sentence so the cryptocurrencies you’re talking about also deserve a lt of knowledge before you can jump into it. Because their some people that they have too much of interest in crypto but they don’t want to seek for knowledge before further, that’s why most of the people are seriously having a issue by the time there into crypto stuff.

Those exchanges that you listed above that you’ve already downloaded them, for now it will be very difficult for you to operate them, because you cannot operate them without having a knowledge about them the only advice I can give you now is for you to go and make your  own personal research about the cryptocurrency stuff, so that you will know the basics things about the crypto aspect and how you can use those exchanges you listed.
