As a crypto-trader, I haven't heard much about XTRABYTES (actually, I don't know this altcoin before). I checked XTRABYTES in coinmarketcap.com, and I found it to be promising. I think that if the devs were able to promote it further and let the crypto-world know everything about it, this will be a successful altcoin.

As of today, its price is at around $0.015. It has a market cap of $6,825,270 , which is ranked 257th. This is pretty low if we think about it, but the thing that caught my attention is its circulating supply and its volume. As of October 30, 2017, it has a circulating supply of 429,500,000 XBY and a total supply of 650,000,000 XBY, which means that there are still around 220.5 million XBY that are untouched. Also, its volume in last 24 hours is $37,796, which means that there were only around 2.36 million XBY or around 0.55% of the total circulating supply that were traded in that course of time. This means that there are a lot of holders who are not yet trading their XBYs.

However, I don't think that it will be a top 10 cryptocurrency in 2018. Top 100 is the most possible and attainable achievement for this cryptocurrency by the end of 2018. But who knows, if the devs are good enough in spreading the words of their project, this coin might climb up the ladder faster.
