All the miners(computers) have to calculate all the different hash codes , and why is such a big transaction bad?
Because it wasn`t really one big transaction, they were spamming the bitcoins around the world with thousands of transactions so there is so much traffic the miners get slower and slower with the calculations.Why was an atack? A simple comparison, if there is a limited amount of water in a town and one of your neighbours pumps all the water in his (swimming)pool no one else get enough water (shower,toilet,cooking, etc...) I think everyone of us would take the water back...?
