True. Bitcoin is more portable compared to gold.
But withstanding the test of time, gold and silver has been the only "real money" for 5000 years.

The digital revolution that we are experiencing is exciting and is also changing money as we see and use it.
I would suggest to try and acquire both BTC and some gold/silver if you can get hold of it.

Both are better storage of your economic energy than fiat for long term.
