I have a similar Mac, a 2013er. I love that machine so much that I bought another, nearly the exact copy of it, a few years ago. Currently I can not imagine that I will need a better/newer Mac or another modern machine. However I am old/older now and had my share on "I need a new computer/laptop every few years".
Yep, same here too. Worked as a freelancer for 15 years with one company and now trying to find a new contract (with only a small network) is pretty hard (can only do remote jobs due to a handicap).
I agree. Nobody at any time promised anything. If you invested early, it was a high risk that the whole cryptocurrency could just have imploded and actually for many it did (BTC and Mt.Gox or lost wallets). Now a few years later it pays out for those who cared early about it. Congratulations for those.
I always liked Hetzner and I have a few dedicated servers there. Their service was always fast and very competent. However they are not soo cheap compared to other hosters anymore.
