It is said That Raiblocks will be New Bitcoin of 2k18. I personally think that $xrb will hit 100$ in Q2 of 2018.
What is Raiblocks(xrb):
RaiBlocks $xrb is IOTA technology (DAG based, like the Tangle). No fees, instant transactions, no miners, true centralization ( no dependency on miners like Bitcoins), the most energy efficient, unlimited scaling. It is the future.Its currently more production ready than IOTA because it works already without a coordinator.
I have been following XRB since may 2017. Best part about XRB is that almost everyday, there are improvements being made to the code! It is Going to be listed on many exchanges in next year.
My Suggesion: HODL $xrb
It is just my opinion and Final Decision is Yours.. Have a Great Day.
