First, to choose, I will consider the ability to generate profits, suitable and long-term time plans, volatility levels... both types of assets are suitable for the above factors, then I will choose real estate as the more reliable choice, real estate itself is a reliable, intuitive type and suitable for any situation, except for real estate that is chosen for investment because it has a very poor position. The value of profit fluctuations, real estate will be at a safe level, bitcoin will have a maximum value in the future but it can be complicated in the way you hold or preserve it.
Reliability: I would choose real estate. Profitability: I would choose bitcoin
It is not recommended to own property if your financial capacity only means a standard salary, for example you are already an employee in a private company with a standard salary in your country of residence and you could experience job termination at any time if the company's financial condition is no longer healthy. Of course, this will be a burden on you in the future if you no longer have income. Instead of wanting to own the property when you make the initial installments, you will be stuck with the installments for the property.
If I had to choose, of course I would choose to invest in cryptocurrency, I would put my money in a coin that has quite good fundamentals, namely bitcoin, even though crypto has quite wild fluctuations, I am quite confident about this digital development in the future. Investing in crypto doesn't require a large amount of capital to own it, just the small amount of money we have, we already have it, it's different with property, we have to have large enough capital for a down payment when initially purchasing the property and paying it in installments over a long period of time.
