Title: May Be At Risk For A Double Spend?????
Post by: Phridom on January 14, 2018, 01:08:21 AM
So I bought Bitcoin the other day from a Bitcoin Kiosk(BitcoinNW) and when I check my blockchain app theres a warning sign that says “may be at risk for a double spend”. I have been buying BTC from this kiosk for awhile and this is a first. Can I send BTC without a problem? Can someone explain why there is a warning?

Can you give us or post here the transaction id of the transaction made from Bitcoin Kiosk?
I guess its only a warning and nothing to worry especially if ots confirmed already, but if the transaction is labeled as "remove/double spent" then its obviously said.

I'm no expert, but I usually see that if a prior transaction using the same funds did not get 6 confirmations before being transferred to you. Maybe the Kiosk transfers funds between multiple addresses automatically?
As long as the transaction to you gets confirmed, it would mean the prior transaction was fully confirmed.

I dont know it is a kiosk and not a human your buying from. Never had sonething like this pop up. Just concerning cause I don’t understand whats going on or what could happen of i send these BTC.

As what I posted its just a kind of warning and nothing to worry unless there's a message on the blockchain that the transaction is "Double Spent".

Anyway its solved now, there's nothing to worry anymore. Just edit the title of the thread [SOLVED]

You get different data displayed to you, depending on which blockchain explorer you use. What probably happened when you purchased Bitcoin was that the hot wallet was funded to fulfill your order, and then spent immediately to your wallet. In your case, the address 1CFAgVzrF5LSaYbE4L9ZFX1k8SYSaQ7FhA was funded only two hours before your tx.

Some merchants/services still take the old recommended "6 confirmation" rule before they consider funds to be safe from double spend risks, especially if it's a lot of coin... I believe at current difficulty/network security, even 1 confirmation is enough for most transactions. Even 2 would be considered realistically unfeasible to try double spend.
