bitcoin is a virtual asset (or currency , whatever..) and while being mined , it wastes huge amounts of power . every transaction on the blockchain needs lots of power (real power , not virtual) .compare that to any other fiat transaction or even other types of crypto transactions which need negligible amount of electricity .

Thats not how it works. Bitcoin doesnt waste ANY energy. It USES the energy. None is wasted. It all goes to securing the protocol. Bitcoin is the most secure network in human history because all that energy is USED to secure it.

Also the energy use has nothing to do with transactions. The energy used secures the network. Bitcoin could use a thousand times as much energy or a thousand times less energy and still do the same transactions. Transactions =\= energy. Energy usage is dictated by the economics of mining rewards, not the number of transactions. The only reason bitcoin mining uses a lot of energy is because the economics of the bitcoin network allows mining to use that much energy and be profitable. There is always more economic output in Bitcoin mining and there is economic/power input.

As for fiat, well that uses an enormous amount of energy, far more than Bitcoin. So if you're comparing Bitcoin energy used to fiat energy use Bitcoin wins by a long shot.

And you mention crypto as well, well no altcoins are money, they are tokens mostly for apps, or failed attempts to compete with bitcoin so it doesn't even make sense to compare them to Bitcoin because they cant do what Bitcoin does.
