Yes, it all comes down to personal preference when it comes to choosing an investment. If someone has a better understanding of real estate investment, then they should look for a suitable property that fits their capital. On the other hand, if someone is more knowledgeable about cryptocurrencies, they can invest in multiple cryptocurrencies available in the market to diversify their capital.
It does not depends on the field that successful field will give you profit and less successful will not give you any profit but the main thing is your interest and your experience. It totally depends on you that what you can easily manage and from which field you can get profit by using your skills.
If you are experienced trader and investor in crypto then don't participate in real estate but continue your journey of success within your desire field. Real estate and cryptocurrency investment both are full of advantages but both requires talents and expertise so you should choose that field about which you know more better.
I'm not sure if I was clear in my above statement, but I never suggested choosing a field with guaranteed success or profitability. What I meant was that the choice of investment depends on the investor. If you base your investment decision on the likelihood of success, you run the risk of failing if the investment doesn't go as planned.
