I store it using my wallet but I have some of it at my other wallet so if in case my other wallet will be hacked then I will have some.But I also invest it so that it will grow and be able to convert it into some cash for many purposes.
Everyone is storing their coins in their specific wallets. That is plain obvious, but by answering 'how to you store your bitcoins' is quite very specific and straightforward. A very good question indeed, this will help new people here in the community.
Having multiple wallets is quite good but, being hacked is on human error. You might not confirmed all the necessary things to have it secured or you used a not so good wallet.
