Like bitcoin, Tellurium is distinct, rare, divisible, and supply-constrained.  It is more supply-constrained than gold, and it has a real-world use that determines its value in terms of joules of energy instead of personal opinion or speculation.  Unlike bitcoin which requires energy, it creates energy which determines its value. 1 gram Tellurium will help produce about 1000 kWh in the 30-year lifetime of a CdTe solar cell before needing to be recycled.  It is currently the lowest-cost method of producing energy in desert-like conditions.  Likewise, a gram of silver in the contacts is required to produce each 1000 kWh of silicon solar cell electricity. silicon solar is the low-cost leader on roof-tops and more northern latitudes. They have been looking for a silver substitute for 40 years but have not had any economic success with alternatives.  So silver and tellurium have equal energy-production value and therefore might arguably be justified in having the same price based on energy production, especially if silicon solar cells continue in their expansion. They will be 50% of silver's use in 5 to 10 years.  As copper mines switch to newer technologies, the older methods that allowed for tellurium extraction are no longer feasible.  Tellurium and silver supply (price) will determine how many solar cells are made for the next 20 years as other technologies take up the slack.  As solar cell production costs reach $0.05/kWh over 30 year lifetimes and if tellurium and silver consume 5% of this production cost, then 1000kWh*$0.0025/kWh = $2.5 per gram value of Te and silver based on their energy-production capability, about 5 times more than silver's current price and 20 times tellurium's. So this $130 bar I offer is arguably worth $2,600 in a real sense.  When bitcoin hits $10,000, I'll buy back my sold tellurium.
