that sounds a bit FUD-dy. 51% allows you to make a double-spend, not "absolutely rig" the blockchain. even with 100% hashrate you won't be able to spend bitcoins without having a private key.
If another user broke the guidelines (such as by accusing you of shilling) and we missed it, you're welcome to let us know by emailing [email protected]. Or by simply flagging the comment, which usually brings it to a moderator's attention.
In the case of that particular comment, your use of hyperbole intensified the effect. "I’ve had enough negative experiences with you for one life" is the sort of thing said by lovers who are about to become exes. Ditto for "I’m not going to chat with you just for you to call me an X again", and so on. This language is way, way too intense for an internet forum disagreement. If you go there, then on a meta level you're communicating something much more personal than the format calls for. Even if the other user did treat you unfairly in the past, you end up positioning yourself as the one who is most out of line, and your comment is likely to strike most readers the way it struck me.
If I’d said “you’re an X person” or “you’re Y”, I would understand. But I didn’t do that.
I would also like to point out that my complaint about them interpreting my words in bad faith, a pejorative according to you, was exactly what they were doing in that comment, as they literally made up a weak argument on my behalf and then shot it down. (I also must complain about the FUD bit, which I’d argue is similar to calling me a shill).
Next time I’ll just flag and move on I guess, but I genuinely do not understand what you’re on about here.
Very little blockchain activity happens “on chain”, and absolutely none of the buying/selling to and from other currencies (including USD) does, because thats not possible. Instead most activity happens on exchanges, which hold onto coins for the user and track account balance in a SQL database just like a traditional exchange. Only if a user moves between exchanges or takes possession of their own coins (a rare occurrence) does an on chain transaction happen, otherwise the rest happens in a SQL database somewhere.
These exchanges are absolutely full of straight up fraud, with some analysts claiming up to 95% faked trade volume. Most exchanges trade on their own account, sometimes badly, and the seediest didn’t even require that you create 2 accounts to wash trade. In this case the on chain transactions aren’t rigged, but the price sure is.
Note: these are the exchanges that also famously get robbed (or “robbed”) and go bankrupt with their clients money. Examples famously include Quadrigacx, Mt. Gox, and others.
