I think we should trust btc because it's backed by blockchain technology, which in turn is backed by science, mathematics and cryptography.
of course we can trust bitcoins in my opinion, i think it can also make you profit so it is beneficial for you to have it
I don't think you can say you "trust" bitcoin, it's not a person to be trusted or not. You can believe in it being successful? But yeah, tho, it doesn't depend on the bitcoin itself.
