You are assuming it is a bad investment based on what? If you bought silver during the spike when it reached 47 $ per ounce or even at any price between 30 and 40 $, it would have been a really poor investment since it does not earn any interest just like gold and platinum..
It is all about timing.. If you bought at 14 last year or even now you will be rewarded, however the new upward cycle might take time to materialize with metals..
I would not be surprised if the next spike reaches 60/ounce.. How long would it take is anybody’s guess.. You need to have patience for the long haul..
Your money could be invested into other things such as crypto currencies or bonds, which would yeild in alot more money. So in conclusion, dont invest into silver.
