economists only understand the old economic theory they get from their lectures...
while Bitcoin is a new thing that they can't understand with their theory that's why they always associate Bitcoin with tulipmania. if they care about people then they will definitely say Bitcoin is the right choice for investing and also transacting large amounts.
not only that. they also think bitcoin is too risky an investment, because it looks like a big bubble. nor can we assume that their choice is wrong. because in fact it is. but what I regret is that they only see that extent. economists don't see the full potential of blockchain. they just see bitcoin as a threat. but turn a blind eye to the underlying technology.
