since ancient times until now gold and silver have always been attractive and remain used as an investment tool until now. because of its beauty and value, which continues to increase, people like to invest in gold. although the increase every year is only 5%. but the value of gold has never dropped. so investing in gold is very safe.
Gold and silver is quite a good investment if we plan to hold it for 10 years, imagine how much it cost then but it is not a good investment if you want to gain some profit in less than a year. I would say, bitcoin is still the best profitable token in terms of investment.
