save on monero or whatever coin you believe.
gold and silver is just not worth it except if you have like a million dollar.
I think that's not a good way. The reason might be for the best investment is home or bitcoin or perhaps gold. Because those 3 things I'm sure and tested very good profits and certain, so if you want to get an advantage then bitcoin, House/land, and gold is the best possible way. but keep in mind, it should be invested well and you have to be patient to wait. Because of the investment it's something that has to wait
