Hi.

Sorry if this seems a little odd, but I'm a bit old school. I was into crypto from around 2010 to around 2014, and have just dabbled with it here and there since then.

All I really know about crypto storage is downloading the official wallet and backing up the wallet.dat file.

A lot of coins I see don't operate in this way any more. I just downloaded the Exodus wallet which allows you to store many coins all in one wallet. It sounds like a great idea, however, I am unsure regarding the security around it. How exactly do I back any of these coins up that I mine/buy on exchanges and send to the Exodus wallet? I set up a password within the software, and backed up the 12 words it gives you for recovery, but what if the company goes bust, which lets face it is very likely in this game. How would I actually physically back up my various crypto assets? I've tried to find a answer online but can't find one. Thanks.

I'm three years behind on Bitcoin Core. Does anyone know if there is a quicker way to download the blockchain other than using the Bitcoin Core software? It's running far too slow.
Thanks.
