To take examples from history. Tesla was visionary, enthusiast and all-around nice guy and where did it get him - died in poverty. While Edisson being A-grade douchebag was a millionaire and by being D-bag still managed to sell and advertise Humanity comforts of electricity propelling it in the world we know today. Same with crypto - until there won't be some "Edisson" to sell Humanity comforts of Bitcoin some other cryptocurrency or products related to it, it will be just a side-show curiosity it is now, and with a business acumen to do it i believe he would be A-grade D-bag scammer, lier and all the things most people don't like. But hey! It's life.
