BTC1 is a decent amount and I understand that you are frustrated. Who else won't be?
But hey, it's just 24h ago that they aren't responding and you considered it as a scam already knowing the reputation they already built?
What about waiting for more days? You didn't even gave them a chance to explained what really happen and just began crying and calling them scam? You will even attempt to spread words about them being a scam without waiting where this case will end up.
What if it will resolved? How can you clean the damages you spread out in various crypto forums?
We are with you here in bitcointalk if that was proven to be scam. For now, hold your horses and stop crying.
... i came to the conclusion that they stole a lot of bitcoins per day from random clients. The system is very old, I cant be the first that get this problem and such a serious error could not have arisen just now.
I know it work for some people, but to me they really stoled me by now.
Libel.
You can say Libel but im a programmer and this type of situation if ocurr once, it will ocurr more then once by functionality, just need time. Im just the first public report.
If they solve I appreciate it, apologize and delete. Until then we know that this kind of bug is no joke at this stage of the system and may not have hit just the only user who reported in public.
Now if they get damage from a post that reported having this issue with them, it's more than fair to me. And at the end of the story let everyone know the result of a problem that actually existed.
Is there a possibility that it is all a misunderstanding and they are not answering me because whoever answers is doing something else? Maybe so, so from the beginning I expressed conditions in case they solve.
First: Bitcointalk doesn't ban scammers. That's important to know when using this website.
Maybe delete his announce or put an signal.
I'm glad you got the issue resolved just like every other user (including myself) assured you above. Chipmixer aren't like the average companies we have out there, they put their reputation above any profit and won't engaging in stealing users fund that's why, we all had confidence when defending them that the issue was simply a misunderstanding that can be resolved and I'm glad it did get resolved. Sorry for the inconvenience though.
