HextraCoin

HextraCoin (hextracoin.com / @hextracoin)

HextraCoin (also styled Hextracoin) is a name that has been used online for a cryptocurrency-themed “investment” or “lending” program that circulated primarily in 2017–2018, promising high, fixed returns to participants. Contemporary third-party reviews and user reports frequently described it as a Ponzi/pyramid-style scheme rather than a conventional cryptocurrency project with independently verifiable products or technology.

Website status and domain information

• hextracoin.com is reported by site-monitoring/reputation services as not functioning (“web server is down”) and/or effectively inactive/parked in recent crawls. (scamadviser.com)
• The related domain hextracoin.co is listed in WHOIS as created on 2017-09-09, with ParkLogic name servers and an expiry of 2026-09-08, which is consistent with a parked/monetized domain setup. (whois.com)

What HextraCoin was described as (historical)

Third-party analyses published during the 2017 crypto boom characterized “HextraCoin” as:

• an “ICO lending” style program offering very high advertised returns (e.g., up to roughly 48% per month in some descriptions), coupled with referral incentives—features commonly associated with HYIP/MLM-style offerings. (behindmlm.com)
• a project that did not clearly identify its operators (i.e., no reliable public ownership/team disclosure on the website, as reported by reviewers). (behindmlm.com)

Reported collapse / suspension of withdrawals

A prominent critical write-up reported that withdrawals/ROI payments were suspended on 2018-01-02, with the project attributing the interruption to a “cyber attack” and promising a return on 2018-01-09. (behindmlm.com)
User discussions from late 2017 similarly contain complaints consistent with delayed or missing withdrawals. (mmo4me.com)

Social media (X/Twitter) account noted by the user

You referenced the X account @hextracoin (shown as x.com/hextracoin). In this environment, the account’s profile contents could not be reliably retrieved from X directly, so no definitive description of the account owner or its current activity can be confirmed here from primary X data. (Historically, promotional campaigns for “Hextracoin” also used other Twitter handles, such as @HextracoinT, in 2017 bounty/airdrop posts.) (bitcointalk.org)

Summary

On the available public record, HextraCoin most plausibly refers to an inactive/defunct crypto “lending/ROI” scheme from 2017–2018, widely alleged by third-party commentators to be Ponzi/pyramid-like, with unclear operators, and with reports of withdrawal suspension/collapse in early January 2018.
