I don't think this kind of strategy won't work anymore due to its price and popularity right now. Unlike before where the price is very low because it isn't known by people and and a few want to use them. It's better to wait to some things that is newly launch like altcoins, maybe, that will last years.
We complain when the price is low, we all know that popular materials gold itself goes down by its price sometime. it happens in everything. so what we have to do is we must have patience so that the price goes high again and we can reap the benefit from it. reason why bitcoin is best part of investment is simple : we get profit from it by holding the coin, if you are smarter enough by trading you can earn well.
