OMG XEM is really going to 3$ in short term, chart looks like is going to explode, probably due catapult mainnet upgrade. Is going nuts.
That would mean a marketcap of 27b...a little optimistic don't you think?

Optimistic? This is crypto. Crypto is ridiculous bullish.
I agree with this chart
https://www.tradingview.com/chart/XEMBTC/BnBDyT98/It is really possible to reach 3$, IF Ethereum did why not XEM? Maybe by the time XEM is a 27B, Ethereum is at 100B. I'm not saying it will surpass Ethereum... both could go up at the same time.
