Not only exchange. Durability is also one of the major factor, you want to have the money/currency useful even after few years, and if it's not relevant at that time, you can't use it as currency.
Just like these credit card reward points and all. What makes a currency currency is whether it'll be relevant a century after it was acquired or not. Can we be sure about it in case of bitcoin?

I didn't get the chance to delete the comment once I came to know that it was considered a spam.
I don't want to go into details how someone posting "Informative Text" image is not a spam. But, saying it's a good post and I've appreciated the post by upvoting is spam.
The only thing I'm saying is, as per https://www.steem.center/index.php?title=Flag, The author should be given sufficient time to respond and correct their mistake or prove ownership of the content. And as I couldn't delete my comment, I corrected it by editing.
It's just that it's very generous of you to flag a corrected comment.
YES, i was very generous to flag you at only 10% (which means less than 0.01 SBD and no effect on your reputation) and give you the possibility not make that mistake again ;-)
Do not make such spammy comments, you'll be flagged
Thanks for the information, had seen many such comments on few other posts. Guilty sorry and corrected.
Next time read the blog on which you are commenting. I know you did not read it, because if you would have noticed the paragraph headed "Important" you would not have done what you did! Before you edited it, you wrote "Nice Post". That's exactly the kind of words to get you flagged.
