One of major strong points in crypto-currencies that holder can keep it in a wallet that is safely stored on media, and that is not connected to any third party and not managed by third party.

Now, companies, just like always, they try to bind the user to their services, so they offer to them wallets, and services of management of wallets.

That is wrong. So don't.

There are here many people in knowledge, find somebody in your country and let him help you ensure the security of your wallet. In general, it requires you to know how to save public and private keys and where to store such keys.

I recommend always to encrypt the data that you are storing. You can store public and private keys even on smallest size USB flash disk, you can store it on hard disks, even in pictures.

In general, you can also print it on paper, and store it in a bank safe.

You can put it under the carpet.

But don't keep it with third parties.

Just ask yourself, who do you really know there?

Who can you catch on the collar if something happens?

Do your basics, and learn what is crypto-currency and never store bitcoin on remote wallets, unless that is amount that you can afford to loose without any consequences.
