The present scale of Bitcoin is too small, even a big retail investor can affect the price. As I repeatedly stated before, there is strong support at $ 600, a lot of funds are ready to get into play when the price is low. So, don’t go short. However, there is no sustained power in the market, so it won’t rise either in the short run. Litecoin is stronger than bitcoin as far as the price movement is concerned, but the pressure above is too much, the line of RMB120 / $ 20 difficult to break. Doge continued to fall, don’t touch it, wait for the next buying opportunity. Altcoins are active today with blackcoin as the lead. I am firmly opposed to buying high.taking  yestodays'article's speculation philosophy: "Do not try to kiss every woman”. Altcoin index is 8.87, up 0.5%, altcion index 2 is 2.92, down 0.2%. Since virturex data is wrong, altcoin index could not be calculated yesterday. Yesterday altcoin index actually declined, and there is a rebound today. Overall, altcoin index below 3 can be considered a low level. You can buy a little bit of altcoin that dived sharply recently.
