i'm prefer to invest in ethereum, after in 2017 hit new ATH i don't is imposible Ethereum can hit another new ATH and passed 2017 ATH, this is just my speculation about ethereum price in future
You made it right. Actually, Ethereum could still make another ATH but not at this time, it soon to have a good moment and Bitcoin also will move. It is just the market today that seems in the struggles and it needs time to recover.
We have also not to disregard of LTC can do since it is one of the top 10 altcoins in the market. It might surprise you somehow of this particular coin will rise and sadly you'd never make some investment in it.
