Would having 70 times less volume mean you wouldn't need to pay to store your stack?
if so then that would be one reason you would swap your silver for gold.
is your silver in the form of semi-numi coins with a premium? be a shame if you got your silver one day and it was all toned and blotchy.
the possibility of tarnish would be a good reason to swap for gold.
is there even the slightest chance that silver, being an industrial metal is in oversupply and could one day fall off the pm charts?
if so then that's another reason to swap.
I recently started to make a switch to gold, mostly because I could see a problem building up in the future, too much volume for value, I already stack an industrial metal in scrap copper, I feel a bit like a gold miner, I get free copper as a by-product of chasing gold in electronics, gold miners get free silver as a by-product of chasing gold in ore.
If you mostly bought silver at the higher end then what makes it worse is your not even holding it, so you invested in something that's somewhere that's going nowhere.
So to put some spark into your investment, change it up to at least give you personal entertainment.
with your cashed in silver you can become a born again stacker whilst swapping the fiat back into gold.
you might start a little collection, gold coins are great to collect as they don't come with much premium.
a 50 year old gold coin generally has the same premium as a current gold coin.
Unless off-course you wanted to go gold numi's, the good thing about it is you can put all your eggs into one little coin.
Like a genuine $50,000 gold sovereign, instead of say 100 x $500 sovereigns.
that way, if you have false teeth you can carve out the shape of the coin on the top of your dentures, slot the 50k coin in and your money will always do the talking for you.
