It appears fire wood and wood burning stoves could be the next bitcoin.
Long story short do we have good buy ins aside from firewood and wood stoves?
You shouldn't compare a mere wood with a digital currency. Bitcoin is like a special treasure if you don't know this. Firewood replenishes, if the demand for wood becomes very high,in the next 50 years there might be few wood or forest in the world.
What should be used to replace this replenish energies should be solar energy, very pure and free of any contamination or waste.
Its just that in the European country there is little of sun over there,if not solar will have been the next alternative. I live in Africa where there is abundant of sunlight. I have a solar panel on my roof,after buying and installation, yours is to enjoy it. It is durable, long lasting and reliable source of energy. In my country electric power supply if poor and everybody has come up with an alternative to have constant power.
