edit :
i just realize it that you need 30 conf for every coins that you want to store in there,
which mean not only Bitcoin but all of them.
0-25 minutes for 1 conf,
25x30 = 750 Minutes (More or less than 12 Hours) GL trading in there mate
hello_good_sir is completely right:
on average, the time between blocks is 10 minutes. If your fee was to low, it can take a while before you get into a block, but once you're in, you should reach 30 confirmations in ~10 x 30 = 300 minutes (5 hours).
It's all odds and averages tough... It can take longer, but it can also be faster...
I think that 30 blocks should be a nice sample size to say that the average block time in those blocks will be very close to 10 minutes. But still, that is a 5 hour wait for a damned bitcoin transaction. There is no point in using bitcoin at all, then.
No idea why Binance even does this... It makes sense for coins like Steem, ETH or doge which has lower block times, but definitely not for bitcoin.
Op should consult the customer service and tell them to change this. This is the highest amount of confs needed for a deposit by far in all the exchanges.
