Where to accumulate the best cryptocurrency?It's of course my opinion, and few other peoples of course, that XEM and blockchain named NEM is best developed blockchain on the cryptoscene, and it's advandages are not yet fully discovered by the rest of the world. I may be wrong, i'am not a prophet, but this is plan how to accumulate this cryptoccurrency, on which levels. Percentage of accumulation in any stages i left to Your decision, if You are willing to invest. Of course this plan will be invalidated, if XEM start build his wave up from now on.
