Edward Snowden, when inquired about cryptos, answered that "(...) the most interesting are the security tokens like Zcash." Personally, there are 2 kinds of way to look at a project: it's either good, because it is the first of it's kind and therefore the price could go up accordingly with that factor and some money can be made in such window, or it's either great, and has long term prospects as it will provide some service that will be powered by blockchain, and has a great team (which is usually listed on the project website) that will guide the project the way possible. Even though agreeing with Snowden as to the best projects are about security, not to mention that blockchain was created out of the cypherpunk movement, I can't overlook the fact that blockchain can revolutionize nearly all sectors of the service industry, and, therefore, influencing both primary and secondary sectors aswell, bringing reduced costs to our lives.
