Hawk Tuah girl Haliey Welch has opened up about what she's learned from her cryptocurrency debacle - admitting she 'doesn't really understand' how the digital currency works.

What began as a risqué video on a private jet saw Haley Welch catapulted to uncharted levels of fame and fortune.

But after a tumultuous few years which saw her launch her own memecoin that reportedly hit a $490m market cap, only to later lose 90 percent of its value, the star is now reflecting on the highs and lows.

In a new interview with Vanity Fair, the 22-year-old gave her verdict on crypto and explained what she did during her hiatus.

Responding to the interviewer’s admission of “barely” understanding the digital currency, Welch replied: “Yeah, I don’t really understand it much myself. I don’t know.

“It was one of those things that just happened, and I feel sorry for everybody that just lost money…. I don’t know.

“I’ve learned from that. You got to be really careful what you tie your name to, and you definitely need to know what you’re getting yourself into when you agree to do it.”

Asked what else she learned from the experience - and whether she had anything to say to the people who lost their savings - Welch responded: “I would say, personally, what I learned from it…let’s see…I don’t know.

“I just feel really bad for anybody that lost money. All my comments, if you read those, people are like, ‘Oh, well, I lost a great deal of money in this. Now my kids have to go without stuff.

“I don’t know. It makes me feel, like, really sorry for it.”

Welch went on to admit she went off-grid following the scandal for a “much-needed mental health break”.

“I would see my friends. I would go out and eat. That’s really about it,” she detailed. “I don’t ever get out and do much when I’m home. I like being by myself.”

Elsewhere, Welch made her return into the spotlight on Friday (May 2) at a Celebrity Poker Tour (CPT) event in ARIA's PokerGO Studio.

At the table, Welch explained how she was feeling about trying her hand at the new venture, telling PokerNews: "I'm a little nervous. It's a smaller (one-table event), so everyone's going to be watching our table. And I still don't know what I'm doing."

She added: "I'm in the middle of rebranding right now," she continued. "I've had a lot of time to think. I want to rebrand."

As for what she’s going to do, Welch teased: "I guess you'll have to watch and see."

Watch this space - but whatever you do, maybe think twice before sinking your life savings into this one.
