What you say may make sense but I am still not convinced, or at least I refuse to believe that the only thing the crypto world has potential for is speculation, something that is so normal on the fiat side. I understand that there are legal obstacles among companies that may choose to use cryptocurrencies for their productive activities but that does not limit their use as we know that depending on the crypto that is used is difficult (not to say impossible) to be confiscated these resources by some central entity, we know that and we must spread among those who do not know the qualities of decentralized digital currencies.
