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).
If there were a global catastrophe for altcoins after which only 5 alts would survive Ethereum would be one of them. Yes it has lost 50% of its recent price, but look at other coins and you'll see that all of them were affected almost to the same degree. Such things happen in the cryptoworld but we know from our experience that the full recovery and subsequent rising are inevitable for good coins like ETH.
