Nano has growed a lot last year, due to bitcoin big and unreal fees for any size of transactions, nowadays bitcoin transactions are very cheap, sure nano still has advantage of being instant, but there is nothing new as i know. Nowadays most of the coins are loosing their value, all expected a lot from consensus, and we are now in the accumulation period, is time to make your personal bets.... the risk is medium-high as the reward might be and became. Nano has as i know a lawsuit due to Bitgrail hack that happened last year.... until some answers and solutions come to those i believe the coin can get back to the grow as before, because a lot people are frozen into those issue and scared to invest.
