I would like to say thank to you everyone that took their time to answer my questions it really helped me to understand more of how these things works.
But one more question can i buy bitcoin here on the forum with my sepa bank account or credit card? or is that not safe maybe? i ask because here i dont see any KYC
The reply above mine already answered your question but I will add that you should be careful because the forum is not a scam free platform. Some people will probably message you seeing how eager you are to buy bitcoin, they will try to use the opportunity to scam you. I'm not saying everyone that message you is a scammer but whatever happens please make sure you buy through escrow if you are to buy from anyone in this forum.
Don't get anything twisted, your preferable links are understandable but for clarity, thorough research should be triggered. The above mentioned criteria will play major roles in guiding OP but that shouldn't mean he will relent and depend on them, rather grabbed the basis and also surf for himself some crucial information to keep himself updated. We know the space is broad but there's numerous sectors to get acquainted to and survive for important winnings.
Doing personal research is very necessary and this forum is also a tool for research thou you can not rely on everything here just like in other research platforms as they are people's opinion based on their own experience. What Mk posted is just a link with additional information that might be helpful to the Op and the readers in general. I understand your point too because some newbies think everything end here without additional research.
