Yes, this is good time to buy Nano (RaiBlocks XRB). I see the price of XRB now is lower than January, 2018 when it reached $34. XRB have good idea when they are building a coin which is "digital currency for the real world – the fast and free way to pay for everything in life". They launched perform own wallet in last Feb, 2018 and i think it will help the price of XRB is increasing very strong. Even i believe the price of XRB will reach $100 in this year.
