You're twisting words. Tipping is not the problem here, it's the cryptocurrencies. If you can't see how people mistrust them then you're probably deeply invested in them yourself.

As long as there is no real value in the real world it will remain inflated by confidence, which reeks of scam. And no one pizza place here or a bitcoin atm there does not make a difference. So far the only real goods and services crypto has traded at scale are on an illegal black market.
