I don't think we can call it greed per se, knowing that there are no certain restrictions for the people in politics to invest in whatever they think will give them profit. After all, they're just people wanting to live a better life like all of us here. If anything, these people are slowly adopting into cryptocurrency and, hopefully, establish some laws which protect the interest of consumers/investors in the cryptoworld. Also, they might, finally, come up with a rather friendly definition of crypto for the benefit of all. I don't see anything wrong in here, TBH, not unless those cryptocurrencies were earned through some form of fraud etc.
