Very impressive and extremely informative. If anything this is precisely the kind of article and information that justifies cryptocurrency investment to those unfamiliar with these virtual assets - especially when compared to the "traditional" stocks, bonds, realty...etc - This makes a great selling point for those still on that proverbial fence for investing in altcoins. Considering the increasing popularity it is entirely possible to go long on some the new coins using this same strategy and viewing the results in July 2018. It would make an interesting follow up for your future article. Perhaps even a series, done every year, 6 months, 3 months...etc - specifically using these top coins and $100 spread.
