It was a good article. Although the price of altcoins are not easily predictable and thus the profits are not that easy to be acquired, this article can help some new traders to get some profit at early stages of their trades. A good strategy yields a good income whether or not the price of the altcoin goes up or down. The strategy showed in this article a worth a try and people should go through it once. Its a good read.
I'm guessing you're talking about different frequencies of trading/investment?
What I liked about the article was the approach to spot trading, I'm guessing you're inferring that this couldn't be used initially and combined with a day trading windows and/or longer term investment strategy?
