I always use my blockchain web wallet to store bitcoins.Also i have one paper wallet to which I rarely sometimes part of bitcoins earned through whatever way(gambling,sig. campaign etc).Paper wallet at the moment is the best way to store bitcoins.
Having too many paper wallets might pose an operational risk. The risk is that you might lose some of them or even forget about those that have too few BTC.
Yeah exactly,I was also thinking to make multiple paperwallets but decided to keep only one due to above things as mentioned by soros.
