Oh my Dears!
Hard fork and hard fork again, there were many hard fork coins of "main" Coins, for example hard fork ones of Bitcoin!
I do not know that Electron coin that is a hard fork of Bitcoin or not but I find out it seems that is that ? but its high price in 2015 used to be 0.009 usd ( two zero numbers)/ coin and now you can buy it here with the price is 0.000002 usd ( five zero numbers )/coin, it means you put 01 usd into it now that equals 4500 usd in 2015 before it delisted out of all exchanges, but may be one day it will be listing again in a boom market of cryptocurrencies when usd will be going crashed!!! You can invest here now, thank you:
