If someone doesn't see the obvious, can they be called blind? Everyone has their own opinion. But know that we continue to make a profit.
Well everyone can have their opinion but that doesn't mean that we have to tolerate the ignorant opinions, they are dangerous and can cripple generations that do not care about people. Also OP, how do you define rationality because I think you don't exactly know what it means.
Go on with what you believe OP and we'll go on living with bitcoin and continue making profits. We don't have to specify why bitcoin has already succeeded but the fact that it had survived in 10 years and has even grown in the years to come will probably tell it all.
And if you talk about bitcoin mining, looks like you're a big fan of Elon. I think you still need to grow more in crypto and make good analysis on the crypto updates. I believe we all have the freedom to express our thoughts and ideas but it should also be based on facts and not from false ones.
