As in the earlier days of Bitcoin, it was really easy to mine it. Though you could have earned 50 BTC only by running the mining software on your personal computer. It didn't remain for so long until one after the other the mining companies began spreading around the world. It turned into such a frenzy that these companies started developing specialised chips (ASIC) to mine this digital currency.
This approach gave the power to the companies like Bitmain etc. For a better understanding what it caused is that today in 2019 more than %80 of the Bitcoins are owned by only the %1 of the network! It was against the purpose of this technology and created a very huge handicap for solo miners, not even mentioning everyday people. Most can only buy it... a fraction of it, to be honest!
