I have a small amount of ethereum, I've noticed since january 2018, the price of the ethereum is at $1000, but now it already lost 50% from its recent price. Is this case normal for ethereum coin? Or it is the end of ethereum. (Sorry my intention was not to create FUD, I'm just curious and new to cryptoworld).
I think you should watch a little bit farther when you check and make up your mind.
In September Ethereum was around 300$, in December we had a crazy run and in January Ethereum broke 1000$.
This is natural market movement. have in mind, that cryptocurrency market is extremely violent and moves like that are common.
So Ethereum has gained over 50% of its value if compare to September.
My advice is to stay calm, because selling now is losing money for sure. Ethereum is far of dead, but the market is down now. Give it some time and change will be here.
