so how about delay times? the time you received bitcoin on your wallet compare with the time was showed on your site is different, 15 seconds or more, and this problem has appeared in this week when your site have problem about forex data quotes.
so you can not told us that this is problem of blockchain.info because I have usedthis wallet over 2 years, and this problem just appeared this week.
I dont ask refund, I ask about this problem.
 I make sure it is not problem of blockchain.info,


we think that the reason is blockchain' problem.  but we will find out the reason more.
and we will test more.
thank you.
I use bitcoin core for bets and I have the same problems from Wednesday. Even with 0.0002 BTC fee.
What you say is bull shit.


This bet was with 18 seconds delay. Fee was 0.00015.

so this is not problem of blockchain.info
P?S: they fixed it, I sent 0.03btc bet and it was showed immediatly


yes, reason of  the problem was double-spending attack .
but now there is not double-spending attack.
and if there will be double-spending attack,  such a delay issues will not be occurred from now on.

thank you.

P.S
our tech team found out the reason of the delay.
the reason  was double spending attack .
but now  these double spending attacks have been disappeared .
we will make the defense policy for these attack.



below are example of the  double spending attack transaction ID's that we received.
