Thinking similarly. Dumps are normal and it won't exceed 25% for ethereum from my perspective. And why is everyone sad? Ethereum came here from $100 and dump from $400 to $290 should not make you upset.
I'm also wondering what's making the ETH lovers down... I have posts from months ago of people worried they overbought when ETH was at $20. Get your profits now and be happy, people!
When the price around $16 to $17 I bought few coins. I thought it would take a long time to reach one decent value. But suddenly it increased I was thinking to buy some more coins, and i thought the price would go down later I buy. But it never comes back under $100. If you are ready to wait for 2 to 3 years then buy and hold. For short trade, i think to choose another alt.
