Mate I wasn't talking about buying BTC and holding it. I meant if you want to buy say 3 eights right now, you'll save money buying all your BTC in one go and then paying for them from your wallet.... everyone has different buying habits mate.
For the record I agree with you that using a wallet is not essential or more "secure" but I disagree that it's pointless. I definitely prefer having my wallet and have definitely saved money with my wallet and I feel safe that I'm not breaking bittylicious ToS. (Although I have also made a couple of buys direct from bittylicious!) So it's not pointless but like I say we all have different habits, no big deal :) Enjoy your night my mate! :)
