OK with all the posts about transactions fees and transaction holds etc .. thought I'd post my experience ..
I have just transferred 2 Bitcoin from my Kraken trading account to my blockchain wallet ... cost of transaction: 0.0005 bitcoin so actual coins received in wallet 1.9995 ... 4 confirmations received within 20 minutes (19 minutes to be exact)
Personally I was expecting maybe a day for the transaction to be completed lol (especially with all the scary posts on the forum) so 20 minutes was pleasantly surprising.
This shows that the bitcoin transactions are completely fast, the stuck only occurs when too many transactions are made at the same time. But, even with so many transactions happening, bitcoins will certainly not face any obstacle when they do 2mb segwit. I'm waiting for it.
