Holding cryptocurrencies inside a self-directed IRA allows growth to be tax-deferred or tax-free depending on whether a traditional or Roth structure is used, so buying, selling, or trading within the account generally doesn’t trigger immediate taxation.

For long-term investors, that tax treatment can preserve more capital for reinvestment and potentially boost overall returns.

Many providers also support rollovers from 401(k)s or existing IRAs into self-directed crypto IRAs, enabling diversification of retirement portfolios with digital assets while maintaining tax efficiency.
