hello,
I like to know where I can create a secure bitcoin wallet where I can keep my bitcoins for years, when I see websites that offer bitcoin wallet, I fear that one day the site no longer exists, and I lose all my bitcoins.
thanks.
You have to make sure to keep your Public/Private Key combination safe if you wish to keep the wallet for years. I recommend generating these yourself and not storing the wallet on a website for long term.
Allowing only the wallet website to hold onto your Keys while a password is your access to your Public/Private Keys means that if the website goes offline, yes you will lose access to those wallet addresses and the funding. If you backup your Public/Private Keys somewhere for each address, you will not lose access when the website goes offline as you can import your funds to another wallet.
