I have been using Web wallet since I started using bitcoin, precisely blockchain.info until recently that a fellow bitcoiner on the forum told me how bad using Web wallet can be for me eventually. He stated paper wallet or desktop wallet as more secured. Still looking into it though and I hope to start utilising one of them soon.
Most of the newbies are using online wallet when they started to use bitcoin because it is the most advisable in newbies that earn a little bit of bitcoin and it is the most easiest to set up. Afterwards if the user wants to upgrade the security of their bitcoin they are upgrading to paper wallet or desktop wallet like this pips.
