I am not really sure with real estate investment have bigger profitable earn from cryptocurrency investment, actually both kinds investment are good but real state take longer time to earn much profitable and need expert marketing strategies how to find the rich person who buy our real estate cash without debt payment ways. Have many taxes payment transaction to paid if want invest on real estate and each country I think taken more than above 5% for fees transaction, you can get less fees transaction when investing in bitcoin exactly with top exchange market have fee under 0.2% and potential earn much profitable in short term.
In other way, investing real estate needed much capital and if you have under $10k not enough yet make investing in real estate and difficult earn high return profitable at short term, but easily with investing in cryptocurrency exactly top altcoin investment adopt short term trading have opportunity profitable earn every day above 4% until 5%.
High profit high risk, low profit low risk, everything is proportional to each other.
Investing in real estate will bring small and slower returns but is obviously much safer than cryptocurrencies. Meanwhile, you can earn 4%, 5% profit per day but you also risk losing everything if something big happens like the exchange collapses or the coin you invested disappears...Everything has its price and it will all depend on each person's preferences to make the right choice.
To be fair: cryptocurrency is the choice of many people because to invest in it, we do not need too much capital and can get rich quickly with small capital. Whereas as you said: real estate requires more initial capital and in my country, it takes at least $100,000 or more to even think about investing in real estate. Capital can be considered the biggest barrier when investing in real estate.
