NEM (XEM) coin looking very interesting to me .Coin rank shows 7 in coinmarketcap.com
Current market cap-1,907,490,000 & Volume -4,376,190
Please provide your suggestion . How is it good for buy and how long time need to hold this two coin
Im not sure about the details but i've seen IOTA being accused of being a scam by pretty smart people on the technical side so im not sure if you want to hold that one for the long term. I think the general hype in crypto things may make it pump on the next altcoin-wave/pump whenever that happens next.
Not sure on XEM so I will not comment on it. Just be very skeptical of alts in general and do due diligence.
