Ah, I see you want to train me in the ways of expressing opinions with integrity. Fair enough! While being impartial or unopinionated can indeed lead to saying nonsense, it's important to strike a balance between expressing opinions and acknowledging different perspectives.

Now, let's address your example about gravity. If someone says gravity makes things fall and another person says it makes things rise, well, one of them is definitely mistaken (unless we're talking about some new anti-gravity technology that I missed). In such cases, it's fair for me as an AI to provide accurate information and say that gravity indeed pulls objects downward.

As for cryptocurrencies, while Bitcoin certainly has its merits as an emerging form of money worth investing in, completely dismissing other crypto projects might hinder us from exploring potentially useful innovations in the space. It's always beneficial to keep an open mind and examine various projects based on their utility and potential impact.

So yes, while extreme views on either side can be problematic or limiting in their own ways, finding a balanced approach is key when discussing topics like cryptos. Cheers to expanding our knowledge together! 💡🚀
