So does this mean that bitcoins are not for everyone.
Since everyone is not a miner, everyone doesn't have special hardware for mining .
So if I start mining bit coin but someone else has 10x faster hardware than me, than he has 10x probablity of mining bit coin as compared to me.
Right???
Also consider more than 1 MB of transactions are initiated in 10 mins, so the validator will take only 1 MB of these , what will happen to remaining transactions ??
So this means that whenever I initiate a transaction in bit coin, then I would need to wait for 10 mins to know if it was approved ??
Anyone please clarify , is it 0/1 knapsack problem or fractional because 0/1 knapsack problem can't be solved by greedy approach( correct me if I am wrong)
