Links to bitcoin millionaires @Denis? You can simply use google for that. If you need motivation to get into crypto, just check the value of BTC 1, 2, 3, 4 years ago and so on, this should be motivation enough? 🙂
I am not saying BitcoinRich.com is not a good site, but I wouldn’t pay to learn something we can learn by reading the dozens of free articles out there @sadman. It’s just a matter of finding reliable and official sources, like medium and hackernoon.
