For now, Bitcoin is too volatile and too risky for a responsible retirement strategy. While it may not be feasible to retire exclusively with cryptocurrency, there are safe ways to add this type of investment to your retirement portfolio. As with other more volatile investment categories, such as stocks, the slow fall strategy will be useful when investing in cryptocurrencies; when you are younger, you have a longer investment time horizon and, historically, longer time horizons are associated with lower volatility. Therefore, as retirement approaches, retirement savings can be gradually transferred to less volatile assets.
The way to continue betting on a strategy of averaging the cost in dollars for all your investments (not just in cryptocurrencies) is to set up automatic transfers from your current account to invest a little in a retirement account every month or, in the case of a 401 (k) account, in each payment period. Generally, the way to decide between investing with an IRA or a Roth IRA is to assess whether your tax rate is likely to be higher now or higher when you retire. If it's higher now, traditional IRA may be the best option. Some investors are perfectly content to design their ideal retirement portfolio, the perfect combination of ETFs containing domestic and foreign stocks and bonds, not to mention investments such as cryptocurrencies and gold.
