Dang 14 hours...the accelerator said success on it..is it proven that it actually does anything?
You shouldn't count 14 hrs but rather an hour passed since you accelerated the 1st unconfirmed transaction ID. Yes, it has proven that many times.
Tried accelerating on all..were successful but still nothing...arghhhh
The issue is they (ViaBTC) haven't mine a single block after you successfully accelerated the transaction. I did the calculation (using an online calculator as below) based on the time you posted to have it successfully accelerated and you missed the chance of having your Tx included in their last found block by 21 minutes only.
At the time of posting this, their last mined block was from 8 hours 33 minutes ago:
https://www.blocktrail.com/BTC/blocks/1 (press Ctrl+f and search for ViaBTC)
The calculation that you missed it by 21 minutes:
https://www.timeanddate.com/date/dateadded.html?d1=04&m1=5&y1=2017&type=sub&ay=&am=&aw=&ad=&h1=03&i1=20&s1=0&ah=8&ai=23&as=&rec=Double check the result with the time you posted here in forum and you'll see that they mined at 3 May 2017, 18:57 and you successfully accelerated at May 03, 2017, 19:18. Both times are forum time.
So ...purchased again from xcoins...which is how i did it originally with the problem one...sent to blockchain....purchased from separate wallet coinbase and sent to blockchain...0 confirmations after 20 mins from xcoins but coinbase one got confirmed in 5 minutes...is it an issue with that wallet or because that theres still a stuck previous transaction?
It's because of previous stuck transaction. Your Tx ID is in the next batch of transactions that will receive confirmations when ViaBTC mines a block.
Update:The stuck input on that Tx is from another Tx that has a long chain of other unconfirmed Tx's. Yes, you should accelerate these as well.
