Buying now thinking that coins are cheap is like buying a lotery ticket. Bottoms are almost imposible to pick, but buying in the down trend is risky, it could go down even further. It is better to see the trend changing from bear to bull and then wait for a buying signal (or a couple of them). You will not buy at the bottom either but it will be less of a bet than buying on the down trend. Remember "The trend is your friend".

According to my technical analysis we could see a rebound from this levels, may be up to 3600 and then it will go down again. That is the short term. On the medium term we could be completing Elliot Wave 4 which means that only Wave 5 left before a long term bear market starts.
