Since this month my transactions are simply failing to process. Some of my transactions are taking 3 hours to process, but one is even worse !! It took a whole day but still unable to complete to process and FAILED. I guess the reason is simple: blocks are getting full.
The problematic transaction, that failed for entire 24 hours: https://blockchain.info/tx/fa7a3e35921fbdf6090f11c2fa58a93627ad65f37bd6d7fd50796e42316efebc
I do believe we should increase the block size, or Bitcoin network stops working grinding to a complete halt.
