That's an awesome collection, and in only 3 years, WOW! So, are you eating ramen noodles every meal and spending all on silver?
Keep stacking and keep saving. I would definitely recommend some diversification into gold bullion also. Some $$$ into cryptos, which you must be doing since you're here on steemit.
To answer the question, you are SAVING and using a tangible asset. That's like asking how much should I save - save ALL that you can.
It does feel like it sometimes,,, the ramen noodle comment. But its worth it to me for freedom. Thanks for the visit and comment.
