If your just holding onto bitcoins, then a hardware wallet is usually considered the most secure option.
Ledger Nano S, they offer a bundle where you can get a backup device.
Trezor One similarly offers bundles that include a backup.
It's the kind of thing where you keep the One on you, and keep the backup in your safe deposit box.
At minimum I would start with :
- Install a wallet on your device (smartphone ie as 'my pocket with every day cash')
The idea of using a smartphone.. It is useful if your running around trying to pay in bitcoins, but android smart phones are not that secure. All it take is one android apps that's a trojans to steal bitcoins. Plugging it into the wrong device could get your bitcoins stolen. Most people don't encrypt their android smart phones. There also many ways to try and bypass the lock screen. Many android phones do not get OS updates, or are slow with updates. Often their backed up to google without 2 step enabled.
I would definitely withdrew the money right away.
Can you tell me if bitcoin can be sold on PayPal somehow? Thanks
Well if you setup an account on coinbase. (or a similar bitcoin exchange) You can set so when you get a bitcoin deposit. It automatically sells off the bitcoins for USD, and deposits the USD into your bank account. Similarly you can sell off bitcoins, and get the USD transferred to paypal.
In the case of coinbase, I think the default exchange can take up to 2 days.
You could also exchange bitcoins for USD at a
bitcoin ATM Exchange.
Any time you use a bitcoin exchange, there a risk that they gets hacked, and you don't get the money. But there no way to exchange bitcoins for USD without this risk. So you just got to know there always a chance you loose the payout.
The downside of exchanging to paypal, is they can charge additional fees. Paypal has been known to freeze accounts if they suspect it's involved with porn.
