I started financially zero and alone, been many businesses but all went down if not, i closed it at least when ROI achieved.
PM is the safest i had been till now and achieved results.
Perhaps i am not good in biz because i used to work in a hard environment, so busy to check my shops.
Until now, i don't predict PM, just moving some if need cash but eventually recover it. When i buy PM most especially some gold, i forget the worth, now i recognized the value. It is less stress on me, no premiums to think because no matter i seek for lowest price, the premiums are outrageous. Some of my stack i bought are in high price, eventually i recover it at the end for its true worth. Of-course, i always look for lowest premium but most of the time i got ripped off. i rather close my eyes each time i turns enthusiastic when buying.
Sometimes web and financial literatures makes stacking more complicated. This is only my experience, Find what suits you, compare your locality and how you move it in times of financial need.
Eg, i got a lot of semi-numis like kooks and pandas, but my locality have a very little market, need to move it via international buyers if needed. But i really love these items, and never planned to move them so i diversified with our local numismatic coins and continued my fashion. If i need a capital, i move some gold, silver is bit hard for me to move quickly because of locality.
I can trade gold in split seconds without stress than silver coins, sometimes need to move gold to buy rolls of lunar and kooks. The ouncer bullion gold coins still suits me for its liquidity. Same with small properties or condos, need to move my gold to cover when i need instant buying plus my cash.
So, it is not the worth of worry, if you are only moving few ounces worth of gold, otherwise stress premiums kills the bug. The loses can be covered by other means by deploying your head sharply in other matters. Anyway, savings makes your stack grow unnoticeably, PM helps value your savings and all uncertainty in different types will just come and visit us anytime.
