Topic: Help me out!! Exam-related questions - page 2. (Read 428 times)

Hello OP, good to see you are interested in Bitcoin from an academic perspective. However this entire thread feels like you are trying to crowd-source your homework solutions from us and there is no point in doing that. Either you want to learn about Bitcoin or you just want to pass an exam. Furthermore, many of the questions have absolutely nothing to do with Bitcoin. So posting this thread in "Bitcoin Discussion" might be pushing it.


How about you try your best to solve the questions and we, as the community, will do our best to correct your work? Sounds better than just us giving you the answers.

If you want to answer these and keep a standard at exams levels I'm pretty sure you can't do it in under 2 hours, OP is just throwing his entire workload onto people on this forum, and if it were for things that are of general knowledge and might help newbie users I could have wasted a few minutes on them but most of them taste shitcoin targeted specific question which has like zero value overall.
Plus a lot of things are just badly worded as questions or statements:


For example, you will be tempted to say False, but when saying false in this case it's because it carries more risks, but could be interpreted as you think it carried "less".

This is just screaming at a wall of text with both pro and against arguments, and it's just like asking somebody do they think Tesla shares will go up. What kind of exam question would that be?

And in part two Q18 looks more like an advert for Filecoin rather than a question  
Anyhow this is indeed 90% altcoin talk, that's where it should go!

LE
I'm really curious, why are some with "PTS" and some "points"?
In both cases, it's like the author got tired at the end of PTS and used points for the last questions.

Why there is the same question two times, and why one has a value of 3 points while the other one only 2?

If you want to study for your test, then the best way is to find the answers by your self. If we provide the answers that will not make you pass your test.

If you want help then post your answers and we can tell you which ones are right or wrong. And if you want someone to answer your test, then you should offer a bounty.

The questions are too much at one go, nobody is going to take out their time they should put into something else to answer 35 questions for you. So many of your questions are not even about bitcoin and so should not be in this section.

I'm sorry but nobody is going to do your research for you, you will have to do it yourself and find answers to your many questions, and as you do that you can ask a few things here that you do not understand, as long as it has to do with bitcoin; for altcoins, ask them in the altcoin section.

From what I see, these questions need quite an amount of research.
So what you though: paste your questions here and let others do your work, right?
But that will not help you, since you'll memorize some things here and there and, after the exam, you will have no idea what was all that about.

Plus, as said, this is not the right place for way more than half of the questions.

You know what OP two things make a spoil of your post.

1. You include altcoins questions knowing Fully that this is bitcoin discussion board and only matters that partains bitcoin alone is permitted for a discussion

2. You make a voluminous pool of questions here and want memebers to start presenting answers to you for your exam ahead, don't you think it's even wrong to get answers leaked before the exam date? How did you even maneuver to get the questions?

The only advised means i know one can pass through in preparing for exams is to sit down and read, search the internet or the forum should incase you need more information on specific areas, but bringing the whole exam questions down here for solutions is a bad way to learning, moreso this could better fit in beginners and help section or altcoins discussion board.

It also allows people on their network to be their own custodians of the data that they store.
