NEM has achieved crosschain transactions, that says alot.
No doubt NEM is one of the best altcoin to invest this year.
I didn't look into NEM yet - there are a lot of people talking about it - so probably one to start taking a look at. Is the code for NEM 'XEM', on Poloniex or is that another coin?
The name is NEM while the ticker symbol is XEM it's not another coin.
