I save my BTC to Paperwallet and Blockchain Web Wallet,what is your choices?
Yes. Paper wallet is a good option however, blockchain web wallet is not safe. Because lately blockchain.info wallet have issues. So for me, its not safe to put your money there. I have stay away from that wallet about a few months ago. Does it gave you control of your private keys? You need to double check with them as I have read that they removed that capability when they released new version of their website. I think you can only import private keys.
i suggest you Download Electrum from Electrum.org i don't know about any of the other versions, but the PC client gives you control over your private keys, so no matter what you can restore your balance to whatever wallet/blockchain you want after the dust settles.
This is one of the best wallet out there that you can used beside the core. I personally used it. If you still have some doubts, I suggest you read this thread:
