real estate and the stock market if you want to invest in it obviously uses a lot of money and a large amount of money, unlike you investing in alt coins you don't need to have a large capital you can already invest in the alt coin which you want.
I agree with you, investing in altcoin allows us to get big profits with small capital even though we have a high risk.
I think investing anywhere has its own advantages and disadvantages, and why people are now more interested in altcoin, I think because this is a new thing and many people are interested in following it.
Especially when in 2017 many people who get very large profits make people hope for a big profit too
