Time Machine works fine here on 10.15.2, I am serving it from a Time Capsule. I replaced the Time Capsule harddrive with a 8TB version.
Even wireless backups work like a charm. I do not use the wireless network from the Time Capsule, but a Linksys Velop network.
It was impossible for me host the backups reliably from a Linux computer though.
In 2012 I learned about Bitcoin and I was denied a MtGox account in 2013, I wanted to buy a few thousand BTC. I don't feel bad about his anymore.
I could not buy Bitcoin for a long time out of spite. Saw it coming by, every time it was worth more and more.
Finally in August 2017 I finally jumped in and made well over 500k Euro in profit, but I kept it too long so I lost 75% of that, I am really glad I took my initial investment out, even though it would have been worth more today.
I did not know anything about trading or reading charts when I started, it would have made a huge difference for me.
Since the beginning of 2018 I have invested most of my free time into understanding trading / markets and programming indicators and market analysis tools. I feel much more confident in trading now and for me it is a good way to make more money.
I like the proverb 'Give a man a fish and he will eat for a day. Teach a man how to fish and you feed him for a lifetime.'
