My biggest problem with bitcoin is that the bitcoin core software is good but downloading the block chain is a very hefty task.
Isn't there any way that we can use Bitcoin qt but not download block chain.
I know there are many wallets out there but still none is comparable to the original.
In the next version I think prunning method will be availible which means we will be able to use our beloved Core original wallet while not having to download the entire blockchain, only about 1GB and 1GB of past transactions should be solid and safe enough against any attacks.
