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 
One, in the mining industry, is rich in power supply, secondly, we do not know when to increase or decrease the price of bitcoin, thirdly, when we sell or buy a token we will pay a high fee, fourth, we can not say our investment is safe because there are so many scammers or hackers, five, when your token is low you will find it difficult to sell
