I store my bitcoin in mycelium mobile wallet. I do not own big amount of btc now so I think it is safer enough. I do not use desktop wallets because I do not have a PC now
If I get more btc, I will store them in a paper wallet as it is one of the safest methods to store btc
I prefer to store my bitcoin in my mobile block chain digital wallet. which is handy and safest way to keep the money online.
I store my coins at an online wallet. I think that is the best to use. And it is also very secure.
Most people are storing it at an online wallet so that is good. Most people trust it too and that is why it is safe.
Some people dont trust it and save it on their own computer.
