Bitcoin price, XRP, Ether rise. Trump just signed an executive order opening Americans’ 401(k) plans to private-equity funds and cryptos.

XRP's value has soared, and Bitcoin's price continues ticking higher. However, only one of these cryptos is likely to have long-term staying power.

This is yet another channel of sustained, long-term demand for Bitcoin that will bid the price higher,” Ryan Rasmussen, head of research at the crypto asset management firm Bitwise, told Fortune. The rise in the crypto and equities markets follows multiple reports that Trump will sign an executive order Thursday midday that will task the Labor Department to reevaluate guidance for fund managers about whether alternative assets can be included in 401 (k)s.
