Re: What do you think are the biggest disadvantages of Bitcoin?
What's preventing Bitcoins from being accepted as mainstream payment forms? I'm working on a new blockchain and would like to learn what drawbacks of Bitcoin urgently need to be improved 
i think the biggest disadvantage of bitcoin is the same as it advantage in other money. we know that the bitcoin is an online cryptocurrencis. and if we say "ONLINE" it talk about the internet or cybernet. then internet needs electricity to start access or to start on this. you got my point ? yeah. if the time comes when there's no electricity bitcoin will be usedless unless if they legalize the bitcoin and make it a country money.
