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.
That is very true. Most people who had cheap eth sold when it was around 500-1000$ and never regretted doing so. This is the right time to buy and when things are good, you sell for new people at a higher cost.
Good investors take advantages from the weaker ones, they are balancing the on how they gained good amount of profits when they heard
some news that will make things move around the project, for those who able to buy ETH last december before the pending fork has announced
and still holding it right now, already got a decent earnings coming from the increase of its value.
