I advise you to post every single problem that you encounter on this thread. Avoid someone who will try to PM you because as soon as they see that you're going to invest 1k Euros then it sounds like a plan to them and easy money since you don't know anything.
So, this isn't just a trading advice but also a tip on how to be safe from anyone that might try to offer help to you but has an intention to scam you.

Good to have you here. I noticed that you got answers to all your questions and if you can return here, you may decide to lock the thread at the down left corner of the post.
Among everything in OP, what caught my interest is "you haven't traded before". I will encourage you to trade. With the money you can afford to lose, you should also please learn how to trade before trading. One funny thing is that almost everyone in the cryptocurrency industry at one time or the other has tried their hands in trading. It is when you have tried, you will understand if trading is actually for you or not.

Welcome to this forum and your presentation as new to the forum is really nice. Suggestion for you as a forum member is to stay aware of this forum and try to inform some forum members yourself as well as learn from the forum. There are several important sections for newbies in which the links have already been shared by other members above, you will follow the posts of those sections regularly. You must spend more time in this forum than all other members because you are new now if you spend more time in forum then you will get interest in this forum then you can definitely make good from this forum. My best wishes for you.

If you want to use Centralized Exchanges, I suggest looking for ones with no Know Your Customer terms.  Know Your Customer will be a headache if you some how trigger it or the website decides to trigger it on you.  Look for either Decentralized Exchanges, a no Know Your Customer ATM if you have any in your area or Centralized Exchanges with no Know Your Customer regulations.

Cryptocurrency is very tempting to trade because at a first glance it looks as if it is easy to make money out of them.  But if you try it out, you realize very quickly it is not as easy as it seems.

So.  I advise you do not trade at all.  You need to acknowledge the GIANT risks involved first.  The best thing to do particularly as a beginner is to Dollar Cost Average only.

There are reputable members in the forum that you can buy Bitcoin from but they are mostly in their respective local boards. I don't know if the Spanish local board have one and even if they do, it is up to you to use that route, maybe through escrow. However, many exchanges have already been suggested by @JeromeTash which you can use to buy Bitcoin without KYC but the only challenge will be if you can use them perfectly as some of them are not straightforward. Maybe you can search youtube on how to use some of those mentioned exchanges, I am confident you will find something that will help.

Those promoters who are promoting Bitcoin as an "ANTI-BANK" or "ANTI-GOVERNMENT" might be promoting it in the wrong way.
Bitcoin wasn't created to be an anti-bank or anti-government at first place.

I mean what kind of question is that? That's a question that can't be answered at all. There are many Bitcoin holders in the world, and why are you asking if I trust them? I can't say that I don't trust them, or I trust them at all. What I will say is that I'm a Bitcoin holder. I'm neither an anti-bank nor anti-government as well.

OP's question is very strange and kind of irrelevant in some ways TBH.

Since bitcoin promotes mostly anti-government, banks, etc.


I am wondering; Do you trust bitcoin holders?

If you come here claiming you have a lot of Btc you should be ready to back up your words with facts to make people believe you  or you will just be considered at best a boaster if not a scammer.

PS: by the way , are you an alt account of original poster? isn't it?

proof?
post a screen or better a video that proves that you hold a looot of BTC
