Here's my prediction:
Within 2 years, ATH for bitcoin will exceed $7,500.
Within 2 years, Litecoin will trade below $10.
Why? Litecoin is an also ran. It offers nothing of value over bitcoin. Sure litecoin is a well run coin, gotta give them props for that, but it's not innovating... and the bitcoin space is already covered by bitcoin.
Ethereum, with all its problems, is at least trying to offer something different.
All lite coin offered was non-asic mining, and that has gone away.
