Re: Is Bitcoin ever be Mainstream?

As an alternative to money yes, as the only currency, don't think so. I even think that Steemit has more chances than Bitcoin.

Bitcoins main problem is that it's not centrally controlled. Currently each transaction on the blockchain uses kWh, equivalent to, on average, 2-3 days of electricity in a UK house.

It's not scalable and it's grossly inefficient because of it.

You don't understand. Not being centralised is the whole point. As for energy waste, do you realise how many computers and buildings full of people are working right now to process that sandwich transaction you made at lunchtime?

Not being centralised leads to gross ineffeciency in the name of "security" which turns out to be a false promise to begin with because bitcoin is so difficult and impractical to use in reality that every single transaction system involves using a third party application run from a centralized location which has far, far less security than the underlying protocol, rendering the entire thing pointless to begin with.

Well perhaps if traditional financial systems weren't so corrupt, people wouldn't feel a need to diversify to something not controlled by the 1%.
