Technical analysis is hopeless enough with Bitcoin, it completely goes out the window when it comes to alts. The only explanation anyone needs is that it'll pump when the people who control them want it to, and collapse when they feel like taking some profit.
Indeed and let simplier the thoughs on this since altcoins will pump if their are so many buys/buy orders will come to them and it will be dumped if majority of its trader selects to dump what they hold and it is proven that this matter really happens and sometimes the one who earn on it is those people who got more budget to spend on manipulating the market this matter is the same on bitcoin movements.
