There is a rumour about hard fork of ETH and the volume in the trading of ETH is aggressively growing .Prices are showing strength .Is it an opportunity to buy on rumour and sell on the news to book profit.
But unfortunately the fork has been delayed for some time that we don't know how long it will be.
When you see the market price dropping, it is a chance to buy the coins with a lower price in the market.
There were few forks of ETH, but most of them turned into a scam fork, constantinople is the most legit fork.
