@ltomo you're welcome, I'm enjoying the conversation.
I do have thoughts to share on cryptocurrency but it's a big one to cover. We may have to approach it in pieces here where I respond to specific inquiries or curiosities as we go.
First, I'd like to recommend that you watch
YouTube and
YouTube. Those are my two favorites videos related to cryptocurrency.
If anybody is curious to dabble with cryptocurrency, the simplest place to start is coinbase.com. Buy $10 of Bitcoin Cash (BCH) and send it to a friend or two for fun (they'll need a BCH wallet of their own with which to receive it). You will then be one of relatively few people on the planet who have done something like that.
Be forewarned that the US Dept of Treasury has their hooks in and standard banking KYC (Know Your Customer) practices apply where you have to show proof of identity for various activities related to cryptocurrencies. Do not store any more value in a 3rd party system like Coinbase than you'd be comfortable losing. If you want to store some fair amount of value in a cryptocurrency, make sure to do it in a hardware wallet that you control. I recommend a
Trezor Model T. Also make sure to
put a copy of the backup seed in a secure location. I store mine in an offsite vault. It is the only thing that can get your money back should you lose your hardware wallet. Cryptocurrency land is deep nerd territory, so be prepared for some clunkiness and frustration during your attempts to use whatever system you end up trying. Cryptocurrencies are not mass market consumer friendly yet.
