I just dont see success and likely government are Same rational and logically thinkers They Will ban btc.
Btc Mining takes just way too much electricity
Fees are expensive yet Still slow no segwit no lighting Network
It just dont smell like success.
When bitcoin has reached the limited supply. no one will know what will happen, I just checked again on coinmarketcap now it has reached 87% of the total bitcoin max supply. bitcoin will be even more successful. it is true that your tought about mining is not completely wrong but if you look at the supply and demand thats will make it bitcoin worth it .
