You are getting yourself confused with the type of long-term assets. Real Estate means investing in buildings and rent them out. While gold is another form of asset under precious metal and the best of all. Bitcoin falls under digital asset. So you should understand the differences. However, it's good that a newbie should only focus on building and growing his bitcoin investment portfolio with DCA for gradual increase weekly or monthly and if you have the funds to lump sum, you do that overtime provided you keep your bitcoin accumulation journey ongoing for 4-10 years and above.
It's bad for you to start thinking to diversify at an early stage of your bitcoin accumulation journey because it will distract you and you can lose focus of achieving your bitcoin target which waa your initial goal. Currently, I think Bitcoin is obe of the best asset that can generate good profit overtime than any other asset. So it's better to stay focus on building and growing your bitcoin portfolio first. However, if you feel that you have more than enough Bitcoin in your possession, you can diversify to any asset of your choice but make sure that you have a good knowledge on how to diversify so that you don't mess things up yourself.
Nothing really compares to Bitcoin, those who have invested in Bitcoin once actually know about Bitcoin. Actually comparing Bitcoin to gold is nothing but stupid. Gold has never in history given investors as much profit as Bitcoin. I myself have experienced this practically, some gold ornaments are purchased for one of my family members at a fixed price at that time. And at the same time I decided not to invest in Bitcoin. As an investment, I converted whatever money I had at that time into Bitcoin. Now when I compare the difference between investing in gold and bitcoin, I see a big difference.
From that time to this time the value of Bitcoin has increased along with the increase in the value of gold, but the increase in the value of gold is nothing compared to the increase in the value of Bitcoin. If I had sold the bitcoin immediately after buying it or if I had bought gold at that time, I would never have made such a huge profit at the present time. I know that investing in Bitcoin involves risking some money, but if I hadn't risked this money, I might not have been successful at this point. I would advise everyone to invest your money in Bitcoin even with some risk of money and one time you will definitely get a smile of success from this investment.
