There are just pumps and no dumps of the Etheruem price. So the traders cannot earn much, there could be some fud about Eth soon.
The Ethereum price is quite strong recently. The price is still around $14 even though the bitcoin price has risen a lot.
The price of Ethereum is $14.6 at the moment. It is almost a new all time high. The volume is low, it means not many people want to sell.
Yea, they are probably hoping for a price increase, which would be a good time to sell ETh.
