I have to disagree if Bitcoin can bring more profit than altcoins, even though in my experience, I made most from Bitcoin. It's either I'm not lucky or using Bitcoin's mindset for holding to long, so whenever my altcoins is rising, I don't sell it immediately.

Yeah I agree becoming Bitcoin maximalist is high likely will reject any new innovation and improvement.

Rather than to be Bitcoin maximalist, better to be decentralization maximalist.
