Your friend gives you a good tip, he probably does not invest in bitcoin but surely know things about cryptocurrency. Gold is a good investment in a long-term investment but it might have some conflict in USD. True that gold and also it has an increasing demand the same as the supply is always limited at some point.

* Properties are not affordable * properties would be a good investment as it could easily give you a passive income that is worth investing.
* Banks are not reliable * I mean that kinda true but still reliable compared to other platforms in my country.
* Investing in Bitcoin & Cryptocurrency * For me the best investment that you could make.

You could send the photo to some of your crypto friends for a word of encouragement or just to give people good tips of where to invest.
