Blockchain is a technology. Crypto curriencies, I will consider them ponzi schemes as long as they are marketed as investments If they are marketed as temporary, volatile, risky currencies, then sure, they are not a scam. The whole crypto industry reeks of sensationalism and trapping gullible idiots who are fed dreams of "returns".
