I recently started dabbling in bitcoin and cryptocurrency this month. I decided to go with Coinbase to fund my first bitcoin purchase since they seemed to be reputable with a lot of good buzz from investors, mainstream financial press, etc. I am really starting to regret this decision. Here is what happened.
1) I funded my Coinbase account for the first time with $1,000 ACH transfer from my bank on January 3, 2018.
2) My online bank statement shows $1,000 was debited out of my bank account from Coinbase the next day on January 4.
3) As of January 9, my Coinbase account still showed the transaction as pending under recent transactions on the Coinbase website.
4) As of January 10, my $1,000 transaction has mysteriously disappeared from the list of transactions Coinbase. There is no trace on the Coinbase website that the transaction has even occurred.
5) My USD wallet on Coinbase still shows $0.00. There is no record anywhere on Coinbase of this $1,000 transaction, as if it never happened. But there IS a record of it on my bank statement that proves it was sent to Coinbase.
6) I will be filing a complaint with my bank first thing in the morning when they open as well as FDIC and CFPB.
7) Is Coinbase a scam? You decide. From where I'm sitting it sure looks like it. Do a Google search for "coinbase scam" and you can find hundreds of similar complaints from Coinbase customers.
Coinbase may be turning into the next Mt. Gox former biggest crypto exchange that went bankrupt and took all its customers money with it! I wish I knew about Mt. Gox beforehand I would have never started into this racket!
Since you didn't post any addresses or transaction id's, i'm going to make an educated guess: My best guess would be that they created a transaction funding your address, but added insufficient fees.
A "default" setup node will drop unconfirmed transactions after 72 hours. I don't know how coinbase's nodes are setup, but if they use the default config, your unconfirmed transaction would have dissapeared after ~3days.
If you can get your hands on the transaction id, i can look it up on my node (i keep more unconfirmed tx's for a longer time) and give you the raw tx to rebroadcast.
If you can't get your hands on the tx id, the address your were funding might work aswell...
please keep in mind, with the amount of information you supplied, i could only make an educated guess... There is no guarantee that this is what really happened. I'm also unfamiliar with the inner workings of coinbase, since i never used them myself...
