If it took little to no effort to get gold, then it wouldn't be valuable. The only reason something like gold is valuable is because it's scarce, and it's scarce because it requires a lot of work to extract. Am I missing something here?
These things are true but not necessarily so. Things can be scarce without being difficult to refine from raw materials (a stamp). Things can be difficult to extract without being particularly scarce (aluminium). Things can be valuable without being scarce (TVs), things can be scarce and not valuable (an original artwork by my 4 year old daughter).
The only thing that makes something valuable is that it is valued by people. People are weird and have lots of different reasons for valuing things. There are lots of things I could burn an insane amount of energy and money on that would not result in anything valued by others.
The idea that something should be valued based on the work that went into creating it is interesting as a hypothetical idea but not something that is very relevant to the actual world we live in.
If anything, you've got it backwards:
> it's scarce because it requires a lot of work to extract
It requires a lot of work to extract because it was so valuable that all the easy-to-extract gold was taken and put in jewelry and vaults.
– boring grey in colour
– not a good conductor of electricity
– not particularly strong, but not ductile or easily malleable either
– not useful for any practical or ornamental purpose
and one special, magical property:
– can be transported over a communications channel
If it somehow acquired any value at all for whatever reason, then anyone wanting to transfer wealth over a long distance could buy some, transmit it, and have the recipient sell it.

Prices depend on supply and demand. Gold is scarce, thus supply is low, and is useful (beautiful, can conduct electricity), thus demand is high.
Bitcoin is scarce, yeah, as it requires a lot of energy to produce it. But it's not really useful for now, people buy it only for speculation. So demand exists, but it might fluctuate a lot.
Platinum for instance was at one point considered the level "above gold", but it has since been overtaken. Gold simply is the better brand. It's the same for Bitcoin versus all other digital currencies.

Speculation itself is useful. Bypassing the financial system is useful.
A price of $18,000 per unit of Bitcoin might sound ridiculous, but it needs to be considered that the market cap of Bitcoin, representing most of the world's cryptocurrency market, is only $200 billion. That is comparable to the assets of a medium-sized US bank.
Uranium fuel takes a lot of effort to refine, but it's still cheaper than gold; partially because it's simply more common in the crust.
