Some whale, some knc miner selling most of their stuff or something, it can be anything lol. Right now its up due to greece, so when I mean everything effects its price, it just means theres a influx of demand coming from different sources all scattered.
not really , i think it is only one thing plus some hype for the grexit, the first thing is the litecoin halving then the drama about the greece
a combination of those two alone can rise the price significantly, then add all the good old news about bitcoin, and you're done, you get that mini pump
usually if bitcoin rise, many who are holding many rubbish coin, get excited and start buy more of those coins that they are holding, it happened many times in the past, but this time the rise isn't so significative...
