The CEO of Tesla and cryptocurrency enthusiast, Elon Musk, has once again spoken in favor of decentralized currency, stating that a day could come when it will eventually replace paper money.

In a recent episode of ARK Invest's FYI podcast hosted by Tasha Keeney, "On the Road to Full Autonomy With Elon Musk," the Tesla CEO spoke about the developments underway at Tesla and about cryptocurrencies, with reference to the future of finance and technology.

When asked about the topic of cryptocurrencies, Musk was taken aback, stating, "Crypto, seriously?" with the interviewer referencing Musk and Twitter's Jack Dorsey's recent chatter about the decentralized currency realm.

Musk stated,

"Bitcoin and Ethereum scammers were so rampant on Twitter I decided to join in and I said at one point I want to buy some Bitcoin. Then my account got suspended cause obviously there was obviously like some automatic rule that if you try to sell bitcoin or something and I was just joking."

In late October, Musk tweeted out, "Wanna buy some Bitcoin?" which sent the cryptocurrency community into a tizzy, many users excited at the prospect of a fruitful collaboration between the Tesla CEO and others such as Binance's Changpeng Zhao.

Following a campaign by Twitter that deleted several bogus accounts for "coordinated manipulation," and promotion of cryptocurrency scams, Musk lauded the website's efforts and went on to state,

"At this point, I want ETH even if it is a scam"

When asked about Jack Dorsey's prediction that the internet will soon see a native currency in Bitcoin, Musk replied stating, "That's interesting."

He added,

" I think that the Bitcoin structure was quite brilliant, its seems like there's some merit to Ethereum as well, and maybe some of the others. But, I'm not sure if it would be a good use of Tesla resources to get into crypto."

Musk added that one of the main downsides of cryptocurrency is the "energy-intensive" nature of production, referring to the mining process. With reference to the same he said,

"There has to be some kind of constraints on the creation of crypto. But it's very energy intensive to create an incremental Bitcoin at this point."

When the topic switched to the nature of Bitcoin transactions, the interviewer stated that cryptocurrencies are not widely used for retail-goods like pizza and coke. To this, Musk replied, "maybe for Coke," referring to the recreational drug that was sold for Bitcoin on marketplaces like the Silk Road, a smudge that the cryptocurrency world is still reeling from.
