Is someone willing to pump this coin price up to 3USD ? 
This weekeend ?
It will take a big group of whales to do that, but I doubt it will reach $3 it will take a few more months before we can reach $3 or more, there's a lot fo problem to be fix and roadmap are not all implemented yet, I don't like this to be a pump and dump coin this is a good coin to be a pump and dump coin. This weekeend ?This isn't even going to hit $1 this year, not at the rate things are progressing.
If the market overall grows 10x during 2018, Electroneum will almost reach 1$ simply keeping up with the average growth. Not unreasonable at all.
If the market doesn't grow, 1$ would indeed require quite a bit of progress, as it'll put Electroneum amongst the top 15 crypto's.
With a strong support, as this project seems to have, I'd say it's very unlikely ETN will underperform relative to the market in 2018.
3$ is a stretch. Either there needs to be a lot of new funds into cryptos this year, or the ETN team needs to do some fabulous work. That'd be like 500x from first ICO price in < 12 months, which is rare.
