There was an exponential bitcoin adoption curve taking place during 2017. Everyone was talking about bitcoin.
At that very moment, incredibly high fees kicked in. This is a feature provided by Bitcoin Core, thanks to the all-new developers (where did these new people come from?) who aren’t very good and refused to increase capacity. As a result of their incompetence, at the very time the technology went mainstream, fees reached over $50 per transaction on average.
Why would they do this? On the surface, the reason they give is social responsibility. They don’t want you bloating the blockchain. Which is a completely bogus reason.
But Rick Falkvinge explains what really happened. The new persons who took over Bitcoin Core (and still maintain it today) simply have other plans.
