What goes down – does not necessarily go up again
A common mistake is searching for crashed coins, in accordance to their value against the Bitcoin, hoping they will return to their glory prices. So newsflash – there are coins which are light years away from their peak levels. Take Aurora for example; in March 2014 an all-time high price of 0.14 Bitcoin for one Aurora was recorded. As of the time of writing, Aurora trades at a 99.9% discount – 0.00014 Bitcoins. Could the (damned) Aurora make a move upwards 1000x? You’ll never know. You surely can’t assume a coin being lower than its peak price is an opportunity rather than a falling knife. There are also coins which disappeared and slowly got out of continuous trading – a scenario defiantly worth considering (especially with the low-cap and volume altcoins).
