It would be really nice to get some clarification/conformation as to how the "button" works.
My speculation is that it pulls funds from a low-balance address to transfer into user's trading address. This itself is a fairly common practice and, personally, is to be expected.
Now, usually, when such low-balance addresses don't have the available funds to make a requested transfer (or the total available funds are below a specified threshold), the transfer doesn't take place. Similar instances where I've seen this practice used will provide an error message informing the user if this is the case, at which time it is up to the provider of the service to add more funds to the address used for payouts.
IF Yobit is handling these sig campaign payouts in this way (and I see no reason for them not to), then the "broken button" is a result of not enough funds in the payout address. The button "works" again when said address is given more funds. The breakdown in communication and resulting confusion is a result of the tech on the site not being complete. When the button doesn't work, there is no message given, no indication at all that the request was sent, but for whatever reason couldn't be completed, nothing. This could be improved greatly.
Again, this is all pure speculation based on what would be considered "best practice" for a system like this. I expect no conformation or explanation from Yobit on the matter, as that apparently isn't their style, but one can always hope...right?
Thanks for your input and clarification. Even if just speculation, it makes perfect sense. If this is the case, I see it much more clearer now. I thought it was just a scrappy line of code that the programmers, or IT, or whomever, have just patched & applied a band aid, of sorts, over and over again instead of re-writing the Ill-performing and broken code.
If it is a depletive wallet that hands out Sig Campaign funds until it runs dry, it would explain the "broken" button many times over. Again, thanks for the input. I guess I need to quit being so hard on the IT guys now, as it is not their fault. Please accept my apology, it is much clearer now. Maybe yobit could update the OP with an explanation of how the payout system works. It would calm a lot of hostilities, and ease people's minds. Thanks again.
