I forgot stablecoin, thank you for reminding me. Stablecoins are also an interesting option as PayPal also has their own stablecoins and X can consider integrating USDT or USDC. I have replaced GROK with Stablecoin in the pool, hope we will have more interesting opinions on this issue.
Mentioning Stablecoins in the poll was a good idea! - that one vote comes from me...
The currency to be integrated in X doesn't need to be a currency suitable as an
investment.
It has to be a currency suitable as
means of payment.
A cryptucurrency (e.g. DOGE) can be - at the same time - a good investment and a bad means of payment.
The fact that Musk likes DOGE as an investment doesn't imply that he likes it as a means of payment.
A means of payment must be stable.
There is a reason why PayPal chose a Stablecoin instead of some cryptocurrency as their means of payment!
The volatility of DOGE and other cryptos prevents them from becoming a suitable means of payment for X.
I'm sure Musk and his advisors are aware of this.
