There’s a Spanish Local board where you can also post your questions and, hopefully, get some answers in Spanish if you wish (see https://bitcointalk.org/index.php?board=27.0). Nevertheless, what you need to do is apply yourself to performing the necessary research, simply by first searching information on each crypto you need to compare, then factor similarities and differences under different prisms (marketcap, history, technology, usage, value, etc. – whatever indicators are relevant to you) and so on. In other words, this is not "el rincón del vago" (Spanish website for copy/pasting essays and homework), and you really need to simply do quite a bit of searching, reading and comparing to start with. Then you can comeback with more specific questions on matters that you did not understand. That’s how I would approach it anyway...
