Lately Mark didn't look so happy any more. Great post. Easy to read.
ps.
Just accidently bumped into your profile just to realize that we seem to share a number of interests :)
In particular that we both share a similar passion towards cryptocurrencies and blockchain technology :)
big fat upvote on the way! :)
I will follow you closely :)
Take care, Piotr
Crypto is both work and entertainment and life and science - all in one.
