Hi, as a fellow miner / holder of Ethereum and some other minor cryptocurrencies, I have to disagree.
You are right that a lot of articles on the internet can be found about people loosing money on crypto exchanges etc., but me personally, I was always satisfied. When I traded one crypto for another, withdraw some for fiat or just kept it there, I never had a single problem. maybe I am just lucky :)

The part about mining software and wallets is true, should be done much better, but hey, againg, it works.

Anyway, interesting point of view, thanks for your atricle :)
